    Jumping in late but in case anyone is curious about FreeFileSync… I’ve been using this for the last two years or so… after having used SyncToy earlier. I was a fan of SyncToy, but FFS is better in several ways:

    1. More configurable.
    2. Significantly faster.
    3. Utilizes shadow copying.

    SyncToy requires users to close pertinent apps first before the corresponding data could be copied / synced. With FFS, you can leave your Office or Quicken files open — and they will still be copied / synced.

  2. Thanks for sharing this information on your sites. This software is really useful for compare and synchronize files but i am using Synkronizer Excel Tool because this is also a free version Tool and compare files quickly.
