So I just installed windows 10, and i had my onedrive folder on an external HDD- and as I am watching it - it AUTOMATICALLY DELETED 15000 OF MY RANDOM FILES AND WHEN I TRY TO RESTORE THEM IN RECYCLE BIN - I GET "ERROR" - PREPARING TO MOVE "DISCOVERED 0 ITEMS".

What do I do? How do I restore these files, when they seem stuck in the recycle bin?

I am dual booting, but even though they are in recycle bin - I canīt see them even on the other install of my Win 8.
So how do I please restore these files?
