Can I safely delete individual files from the Windows File History?
Solution 1:
I don't have any official evidences, but I did this with my backups.
Drawback: file history GUI will still show these deleted files as if they exist, but it will show error on trying to preview or restore them (so links kept in database until cleaned up by date).
If you have multiple versions of a file for different dates, you will still be able to restore it for dates, for which you didn't remove the file, but you'll have pick these specific dates in history GUI (using slider buttons at bottom of window).
Otherwise, it works fine.
