Use the DEL button to delete a file? This is not possible in tixati in noticed.

Also when I delete a file in tixati I would like it to delete the file on the HDD as well, is couldn't find this option either? Is this possible?

IM using
windows 8.1 x64
tixati v1.99

To delete a torrent and files: select it, click Remove button, use Remove And Delete Local Files.
