Folder Sync

Folder Sync is a feature to synchronize files between computers and the FreeAgent drive. It supports automatic and manual synchronization, and it can be used to synchronize as many computers as you want. An example would be a folder with current project files, which you store on the FreeAgent drive, but synchronize with your office PC, notebook and the home computer every time you attach the FreeAgent Go. This solution does not only ensure that you've got an up to date or an almost up to date backup on all computers, but it also creates automatic backups. However, it doesn't protect you from accidental modification of your data: If something went wrong with the project file you're working on, make sure that you do not synchronize it with the FreeAgent.
