I needed a piece of software to maintain my backup of 20 gigs of mp3 on a slave drive. I looked at all the pay options and they seemed to over complicate things for what i needed.
After deciding to try this, the download, install, directory setup and running the programme with around 100 file additions and removals took under 5 minutes in total.
download is less than a meg, footprint is tiny, interface is simple, speed is great.
This is the first time i have EVER been moved to write a review of software. What a great little programme!
