Twin Folders is a file and directory synchronization utility. If you are working on two different computers - for example a desktop and notebook, then you need to keep your work files up-to-date at both computers. Perhaps you do not want to even remember what computer you used last and next time you want to work on either of them. Twin Folders file synchronizer will make the right choice. Run synchronization before or after you use any of your computers and eliminate any concerns.
