FolderMatch
Use FolderMatch to compare and sync your files and folders so you willalways have the most current data. Ideal for people in business, for peoplewho burn CDs, or for anyone who keeps multiple copies of files. Stay in syncwith a button click.

One of the best in its category. I've looked at dozens of these. This is one of the easiest and yet the most powerful.

Excellent! So easy to use, Helps me with everything from checking my html versions, to checking my CD burns. I like the mass file renamer... on top of that, it has an awesome interface.
