Blocks access to all 3rd party apps - which try to gain access to Windows folders (libraries Included). Windows already has predefined rules for its own software - or software installed through Microsoft Store, but - if you download the apps from a site - it's up to you (to test or decide if that software is safe enough - to access Windows files).

If you are sure can trust the 3rd party app, then you can allow it through Controlled Folder Access.

Many Controlled Folder Blocks are harmless. You may ignore most of them unless you are having problems with an app you're trying to run, e.g. I often see blocks for Aomei Backupper that are harmless.
