If you deleted a file, it will be in your Trash. No, don’t look at the bin in your office or room. Go to the Trash menu in the right bar, select the file(s) you want to retrieve and click the Restore icon in the top right corner. Or simply right click the file and select ‘Restore’
If deleted the file permanently from your Trash, send us a mail on firstname.lastname@example.org and we’ll see if we can recover it for you.
