If the Bin contains recovered files on Mac
One or more Recovered Files folders may appear in your Trash after you restart your Mac.
The recovered files are temporary files used by macOS apps. Usually temporary files are deleted by an app when it no longer needs them. If an app quits unexpectedly, it may not be able to delete the temporary files before it quits. When you restart your Mac, macOS moves these temporary files to the Trash.
Check with the developer if you’re not sure how to handle recovered files.
