For the torrent issue, you can remove the '.!ut'; add the torrent to your torrent client, setting the new path and let him do a filecheck of the torrent. After that you can move the torrent files from within the torrent client to another location and it will move only the verified files from the torrent so you can safely remove the possible junk files. For performing batch rename I prefer Thunar's renamer (thunar).
Why would you want to put all you're backups in the same directory ? I use BackInTime for backups and " cp -a backintime /pathToNewFolder " to move my backup folder from one drive to another. Good luck ! -- I use: trisquel.info | ceata.org | fsf.org | riseup.net | duckduckgo.com | eff.org | h-node.com | torproject.org | airvpn.org | flattr.com | skepdic.com |
