Joel said:Yes, the target is the data you want to erase.
The data is not actually erased until the task is run. You can do that by right-clicking the task and select Run Task, or Ctrl-Alt-R on the selected task.
Joel said:There is no such thing as "unused space in the recycle bin." The recycle bin stores files which you want to delete. Emptying the recycle bin deletes those files for real.
Erasing the recycle bin erases the files, instead of deleting them.
Joel said:Files deleting from the recycle bin will act like files deleted anywhere else, that scanning the empty space of the disk will reveal what the contents were. You'll still have to erase the files even if they went to the recycle bin if you want their contents to be irrecoverable.
