Folders and search in Windows 11: a complete guide to finding everything

Alpha Guide » Games » Folders and search in Windows 11: a complete guide to finding everything

If you use Windows 11 daily, knowing how to organize files and mastering folders and search makes all the difference between wasting time searching and finding everything instantly. The system includes several search engines, indexing options, advanced filters, and even artificial intelligence features that, when properly configured, can turn your PC into a kind of local "Google."

This guide will show you all the ways to search for files, folders, and content in Windows 11, how to refine your searches with advanced operators, how to improve index performance, what to do when nothing is found, and how to exclude locations for privacy. We'll also review some powerful third-party programs for searching hard drives and networks, and cover the improvements to Copilot+ PC and semantic indexing.

How search works in Windows 11 and what has changed

Windows 11 relies on a built-in indexing service that crawls configured folders, saving information about file names, paths, dates, sizes, and, in many cases, content, to deliver near-instant results. This is complemented by cloud integration (OneDrive, Outlook, Bing) and, on Copilot+ PCs, more advanced semantic indexing .

In Copilot+ PCs, in addition to standard indexing, a semantic index is created for text files and documents (.txt, .pdf, .docx, .doc, .rtf, .pptx, .ppt, .xls, .xlsx) and for images (.jpg/.jpeg, .png, .gif, .bmp, .ico). Thanks to this, searches are not based solely on literal matches: related concepts are taken into account . For example, if you search for "pasta," the system might suggest files or images related to "lasagna" because it understands the relationship between the two terms.

Everything generated by this semantic indexing is stored only on your device (or on the local storage of a Windows 365 AI-enabled cloud PC). Microsoft states that it does not send this data to its servers or use it to train models , so the improved search does not, in itself, involve sacrificing your privacy.

Semantic indexing is enabled by default in Copilot+ PC, but you can change it from Settings > Privacy and security > Search Windows > Advanced indexing options . From there, you can disable indexing for specific locations or file types if you want to reduce resource consumption or limit what gets indexed.

To ensure the initial indexing completes as quickly as possible , it's best to leave your computer plugged in and the lid open (on laptops) for a while. You can check the indexing status in Settings > Privacy & Security > Windows Search , where you'll see if the process is active, paused, or finished.

Windows Search: The system's universal search engine

Windows Search ( the one you see in the taskbar or Start menu) is the first place most people turn to. It's a universal search engine: it can be used to locate files, folders, applications, settings, and even perform web searches with Bing.

In Windows 11, this search bar can appear as a text box, a magnifying glass icon, a labeled button , or be completely hidden from the taskbar. You can change this in Settings > Personalization > Taskbar , where you'll find four options: hide, icon only, icon with text, or full search box.

Many users prefer not to clutter the taskbar and use keyboard shortcuts . There are several ways to launch a search without using the mouse: the Windows + S key combination , the Windows key followed by typing your query directly into the Start menu, or simply clicking on the Start search box itself.

As you type, the system tries to guess which result is most relevant : if you always open the same Excel file, document, or program, it will gradually appear at the top. It also organizes the results by category (applications, documents, email, web, etc.), and below the text box, you'll see some quick filters (for example, documents only) that you can use to refine your search.

Windows Search can also display content from the cloud (OneDrive, Outlook, and other Microsoft services) and leverage your local search history to prioritize what you use most. All of this is controlled in Settings > Privacy and security > Search permissions , where you can enable or disable cloud search and search history on your device.

File Explorer: Precise search with filters and operators

In addition to the Start menu search box, Windows 11 File Explorer has its own search box in the upper right corner. This is the ideal tool when you want to search within a specific folder or drive, or when you need highly refined searches with advanced filters.

By default, when you type a term in that box, Windows searches the current location (including subfolders, unless you choose otherwise). Although at first glance it seems like a very basic search engine, it actually supports a lot of operators similar to those in Gmail or Google.

The boolean operators They allow you to combine or exclude words in your search. These are the most important ones:
NOT or the minus sign excludes a term (example: dog NOT cat o dog - cat to find files that contain “dog” but not “cat”).
OR expand the search to one or the other term (example: invoice OR receipt).
Double quotation marks They require the exact phrase to appear in that order (example: "annual report").
Parenthesis They indicate that the words inside can go in any order (example: (cat dog) returns names that include both words, regardless of position).

You also have general filters in the form of “field:value”. Some very useful ones are:
date: It allows filtering by creation or modification date with values ​​such as today, yesterday, this week, last month, this year, or a specific date. Example: date:today o fecha:01/01/2024..31/01/2024.
modified: Same as the previous one but only takes into account the modification date.
created: Filter by the original creation date of the file.
size: Filter by size. You can use ranges (e.g. size:>50MB) or categories such as empty, minuscule, small, medium, large, enormous, gigantic.
class: Restricts by file type (document, image, music, video, email, game, saved search, etc.). Example: class:image.
out: filter by extension, for example ext:jpg o ext:pdf.
binder: It lets you specify a particular folder within the search location.
archive: It indicates that only the file name should be considered, not the content.

There are also specific filters by file type that are based on metadata. For example:
slides: number of pages in a presentation (e.g. slides:20).
commentary: searches for text in comments of Word documents (comment: "for review").
artist, album, track, genre: applicable to audio files if they have that metadata filled in.
duration: for music and video, with values ​​such as very short, short, medium, long, very long or exact durations.
year: year associated with songs or films (year: 1990, For example).
orientation, width, height: useful for photos; you can search by orientation or by pixel dimensions.

The key is that you can combine several operators separated by spaces, for example: class:document modified:yesterday NOT draft ext:docx . This makes searching a very precise tool for managing large libraries.

Classic and enhanced indexing: speeding up and expanding search

The search engine relies on an index that Windows maintains in the background . By default, the system primarily indexes Documents, Pictures, Music, and the Desktop, which is usually sufficient for many cases, but falls short if you work on other disks, external drives, or custom folders.

To adjust this behavior, go to Settings > Privacy and security > Windows Search . There you'll see two indexing modes: Classic mode, which focuses on a few locations, and Enhanced mode , which expands indexing to virtually the entire system disk, excluding some critical or system locations to avoid impacting performance.

Enabling enhanced indexing will cause Windows to crawl significantly more content, resulting in more comprehensive searches in both the browser and Universal Search . However, the indexing process can consume more CPU and impact battery life on laptops, especially during the first few hours or days.

From that same screen, you can view the index status , temporarily pause the process if you need maximum performance, and, importantly, access the Advanced Indexing Options . This section is where you can include or exclude specific locations, rebuild the index, or adjust which file types are indexed by content and which only by name.

If you notice that the search is slow or stops finding things you know are there, it's a good idea to review the settings here and, if necessary, rebuild the index to clean up any corruption.

Improve search: cloud, history, resolvers, and index rebuilding

Beyond choosing between classic and enhanced search modes, Windows 11 offers several additional settings to fine-tune search behavior and troubleshoot issues. Starting with cloud integration, you can allow Windows to search services associated with your Microsoft account, such as OneDrive, Outlook, and Bing.

In Settings > Privacy and security > Search permissions , you'll find the toggles for cloud content and search history on this device . Enabling them makes the results more tailored to your habits, prioritizing what you open most often and mixing local and online results when appropriate.

If you notice that search has become unstable, slow, or is failing altogether, you should run the Search and Indexing troubleshooter . To do this, open Settings, go to System > Troubleshoot > Other troubleshooters , and select the Search and Indexing tool. This utility checks services, permissions, index integrity, and other parameters, and offers to apply automatic fixes.

If the index is severely damaged, another helpful step is to rebuild it completely . Go to Settings > Privacy & Security > Windows Search , scroll down to "Related settings," and open the advanced indexing options. In the advanced options window, you'll see a Rebuild button . Clicking it will delete the index and recreate it from scratch, a process that can take several hours depending on the size of the files.

Ideally, you should start the rebuild when you don't need your computer at peak performance , leave it plugged in, and let it run for as long as necessary (Microsoft recommends up to 24 hours for heavily loaded systems). Once it's finished, the search experience usually improves significantly.

Searching from Explorer and from the Start menu: key differences

Although they may seem the same, searching from the Start menu and searching within File Explorer behave differently. The former acts as a quick launcher: it's designed to help you find a program, a specific document, or a system setting in seconds.

In Windows 11, the search bar integrated into the Start menu has been visually updated to match the new design, but it still works the same as in Windows 10: simply open Start and start typing . You'll see suggested apps, recent documents, web results, and other items grouped by type, with tabs to filter if you want to focus only on files, for example.

The Explorer search function, on the other hand, is designed to work within a specific path . You open Explorer (folder icon, "This PC," or Win + E shortcut), navigate to the desired folder or drive, and type in the search box at the top. By default, it searches the current folder and its subfolders, but from the "Search options" button, you can limit the search to the root folder only, include compressed files, search within the contents of files, and more.

In Windows 10, launching a search opened a dedicated "Search Tools" tab in the Ribbon, with options to filter by date, type, size, history, and save searches . In Windows 11, with the redesigned interface, many of these actions are now concentrated in a "Search Options" button located in the toolbar. From there, you can still filter by date, type, size, or location, but the classic option to save a search as a .search-ms file has been removed.

In any case, the combination of both search engines (home and explorer), along with the filtering operators, covers virtually any day-to-day situation, from opening an app with two keys to locating a specific PDF buried in ten subfolders.

Advanced tricks: wildcards, sizes, dates, and saved searches

One of the most useful resources when you don't remember the exact name of a file is the use of wildcards in your search . The asterisk (*) substitutes for any number of characters, so you can formulate queries like soft* to find all files whose name begins with "soft", or *soft* to locate any file that has that string anywhere in its name.

The same wildcard can be used to filter by file extension . Typing *.gif returns all GIF images, while *.mp4 shows your videos in that format. You can combine these wildcards with other filters, for example: *.pdf size:>50MB to find only large PDFs.

Size and date filters are especially useful for freeing up space or finding recent documents. From the Search tab menu (in Windows 10) or from "Search Options" (Windows 11), you can choose predefined size ranges (Empty, Tiny, Small, Medium, Large, Huge, Gigantic) or define a specific range by typing something like size :>500MB in the search box.

For dates, you have relative values ​​like today, yesterday, this week, last month , or directly a range with two dates separated by a colon, something like date:01/01/2023..31/12/2023 . You can also differentiate between modified and created , for example, modified:yesterday for recently edited documents or created:"this month" for new files in the current month.

Windows 10 had a very useful feature: saving searches . After performing a search in the file explorer, the "Search Tools" tab contained a "Save Search" button, which allowed you to save the search as a .search-ms file. This file could be placed on the Desktop or in any folder, and when opened, it would run the search again at that point—very useful if you were working with complex filters.

In Windows 11 this feature as such has been lost, but you can still replicate some of that behavior using shortcuts to the explorer with parameters or by using third-party applications that do allow you to mark recurring searches , such as Everything or some alternative file managers.

Exclude folders from search to gain privacy

Improved indexing is great for finding everything, but you might not want certain sensitive folders to appear in the results every time someone searches for something on your PC. Luckily, Windows 11 lets you exclude specific locations from the search.

To do this, go to Settings > Privacy and security > Windows Search . In the Enhanced Search section, you'll see the "Exclude folders from Enhanced Search" option . From there, you can add folders to the exclusions list by navigating to the desired path in File Explorer and confirming.

The folders you add will be removed from the global index , so the files they contain won't appear in the enhanced search results. This is especially useful if you share your computer with others and want to keep private documents out of the public eye without having to move or encrypt them.

You can always add or remove folders from this list as needed. It's a simple way to balance the convenience of an aggressive disk-wide search with the need to protect certain content.

When Windows can't find anything: corrupt index and solutions

It's possible that, no matter how much you try, Windows 11 might not be able to find files you know are there. If the problem only affects indexed searches (Start menu and File Explorer), the index is probably corrupted or outdated compared to the actual disk space.

Remember that the index is simply a giant "table of contents" with names, paths, and basic properties. When you send a search, the system consults this index instead of scanning the entire disk folder by folder, which saves a lot of time. If this table becomes corrupted, the system loses its reliable view of your files.

When you suspect index corruption, the first step is to open the search box, type "Indexing Options," and access the classic index configuration tool. From there, you can see which locations are included , pause indexing, and, most importantly, access the Advanced Options.

In the advanced options window, you'll find a Rebuild button within the troubleshooting section. After confirming, the current index is deleted, and Windows begins creating a new one. This process can take a while, especially if you have enhanced indexing enabled or if your disk contains millions of files.

While the system is being rebuilt, you may notice that some searches take longer or don't return complete results , but this will normalize as the process progresses. On very large systems, it may be advisable to leave the PC plugged in overnight so the indexer can finish without interruption.

External programs to search for files even faster

Although Windows Search has improved significantly, some users prefer specialized applications for handling complex searches or working with large collections of files. Several popular tools complement (or replace) the native search function with their own indexes and advanced filters.

SearchMyFiles , by Nirsoft, is a portable and comprehensive utility for searching for files in countless ways. It allows you to filter by creation date, modification date, last access date, attributes, content, size, extension, and more. It can even detect duplicate files, files with the same names, or files with the same content, generating lists that you can then export to HTML, CSV, or XML.

Among its options, you can specify folders to scan, folders to exclude, file types, size ranges, or dates … Yes, its interface is quite basic and might be intimidating at first, but in return, it offers an enormous level of control. One of the latest features is the ability to search for text within the content of documents, not just by name; ideal if you remember a phrase but not where you saved it.

Everything is another classic. It's an ultra-fast search engine that creates its own index from the Master File Table (MFT) on NTFS disks. It uses very few resources, takes up only a couple of megabytes, and can display results in real time as you type . It also has filters by file type and a bookmarking system for saving frequently used searches.

It also includes an optional HTTP server, so you can perform remote searches from other computers on the local network or even from outside (if configured properly). Its main limitation is that, while it offers some filters, it doesn't reach the level of sophistication of SearchMyFiles in terms of complex conditions, but in return, it's extremely fast.

WizFile is quite similar to Everything in philosophy: it uses the MFT to scan NTFS disks at high speed and doesn't require a separate database file because it stores the index in memory . Its interface is simple: search box at the top, results below, and options to sort by name, size, or date. It supports both local disks and network shares , making it ideal for file server environments.

Finally, Listary and PowerToys Run are more like "launchers" than traditional search engines. Listary integrates with popular file managers (Total Commander, Directory Opus, XYplorer, etc.) and allows you to search and navigate folders simply by typing , move and copy files more easily, and configure what is included or omitted from the results.

PowerToys Run, included in the Microsoft PowerToys suite, is a universal launcher/search tool that appears with a keyboard shortcut. Originally designed as an application launcher, today, by enabling its integration with Windows Search and adjusting the enhanced indexing, it can find files, folders, settings, and much more, with minimal performance impact.

Find large files and clean up space without complications

If your hard drive is running low, a quick way to free up space is to locate the largest files directly from File Explorer. No installation is required: simply open the drive (for example, C:), go to the search box, and use the appropriate size filter.

You can open the size menu (in the search tab or from the "Size" column header) and choose a category like Large, Huge, or Gigantic . Windows will apply the filter and display only the files that fall within that range. If you want to be more precise, type something like size:>500MB directly into the box , or even combine it with another condition, such as size:>1GB ext:iso.

Beyond personal files, Windows accumulates temporary files, update remnants, and other system files that can take up several gigabytes. The safe way to get rid of them is to use the built-in tools, not to delete them manually. A classic option is to right-click on the C: drive, go to Properties, and click the Cleanup button, which opens the interface to select temporary files, old installation files, Windows Defender cache, etc.

The modern Settings screen also offers equivalent options for analyzing used space and deleting what no longer makes sense to keep. It's the easiest way for the system itself to find and mark everything that's unnecessary , preventing potentially harmful deletions.

By combining these size checks with a small periodic review of downloads, videos, and old backups, it's relatively easy to keep your disk under control without having to resort to aggressive external cleaning utilities.

Mastering folders and searching in Windows 11 takes some time at first, but once you understand where to configure indexing, how to exclude sensitive locations, which operators to use in the file explorer, and what to do when the index malfunctions, the system ceases to be a black box and becomes a highly efficient tool. If you add some lightweight external search engines for extreme cases, you'll always have your files and documents just one or two clicks away, no matter how full your disk is.
