: In many cases, users aren't looking for the file itself but the file extension (like .exe or .pdf). You can unhide these in Windows via Folder Options by unchecking "Hide extensions for known file types". Why Files Are Hidden
Hiding files and folders in Box Drive
Sometimes, you check the "Hidden items" box in Windows, and the file still doesn't appear. This is because the file is flagged as both "Hidden" and a "Protected Operating System File."
: Click on View in the top toolbar, hover over Show , and select Hidden items .
If a file is stubborn or locked by a "Super Hidden" system attribute, use the command line.
Note: Be extremely careful when interacting with operating system files. Deleting them can render your computer unbootable.
