=== Q: There is a directory with the name .Trashcan in my archive directory. Can you explain me its function? === |
|||
A: Files deleted from the archive are put in the Trashcan. Contents of the Trashcan are not deleted by the system and therefore are accounted and to the amount of data stored. To permanently delete the data you have to open the .Trashcan and delete the files. To recover files from the Trashcan move (or rename) the files to a different location outside the Trashcan. |
