Useful programs

Yesterday I began to undertake the time wasting process of trying to get rid of duplicate files and all around condense my multiple copies of backups on my external drive. It actually wasn't as painful and cumbersome as I had thought it would be due to two programs. SpaceMonger- via Ken is a GREAT visual file explorer- it displays the space taken by files/folders visually as blocks. It even showed me archived files that wouldn't show up in MS explorer even when 'Show hidden folders' was turned on. Then ViceVersa Free is a great program that allows you to compare folders and synchronize files, just make sure you read the Help file before starting. And yes, I am sure that there is a Linux program or script that does all of this.
