I'm disappointed by this software. It says it's free and I use it for my own personal backup. I have some folders with lots of files and after a week it told me my usage was too much and I have to wait a month for usage to go down. This sucks! This isn't free. I like to keep my personal files with me and Sync between my different computers using my U3 drive. If it's free for personal use there shouldn't be such a low usage setting.
