As a teacher, I am finding Sync Folders to be invaluable for keeping my lesson files and students work files up-to-date between my home computer, my flash drive and my office computer. I do not need to worry about losing track of any changes made to files at any point. Sync Folders works seamlessly in the background, leaving me free to concentrate on my lesson plans and deal with the more important aspects of teaching. I recommend Sync Folders for its ease of use, trouble-free file syncing and unobtrusive operation.
