The storage libraries (such as Pictures, Music, and Videos) in Windows provide access to folders created to store different types of files. Many apps only have access to the media files found in these storage libraries; they don't have access to files saved in other locations like local drives.
Get folder suggestions
Folder suggestions scans your device to identify folders containing content that could be worth adding to one or more of the storage libraries. It only scans the areas found in your Windows account profile (like folders on your Desktop), or 'public' areas of your device (areas outside of account profiles and other local drives). It won't scan any documents, account profiles other than your own, or certain locations including storage libraries and most root folders.
Folder suggestions will show you a list of folders it finds, along with a sampling of thumbnail images to help you understand the content stored inside. Then, you can select which (if any) of the folders you want to add to your storage libraries.
Note: As long as you're using separate Windows account profiles, the files stored in your profile won't be included in the list of folders available to other people who use your PC.
Remove folders from a library
You can remove folders from libraries in File Explorer, or from the settings of some apps that access storage libraries (such as the Photos app, which accesses the Pictures library).
In File Explorer, select View > Navigation pane, and then make sure Navigation pane and Show libraries are selected. In the left pane of File Explorer, browse to Libraries to find the library you want to remove a folder from. Under Library Tools, select Manage > Manage library, select a folder to remove, then select Remove > OK.
In the Photos app, select See more > Settings, and then under Sources select the Close button next to a folder you want the app to stop accessing.
Note: Removing a folder from a library doesn't delete it—it just won't appear in the library anymore.
