I need to sync a file between my computer and a USB stick. The sync needs to happen in real time, as in when the right file changes sync to the left file and vice versa. I tried looking at Task Scheduler but there doesn't seem to be a way to add a trigger that detects a file change. I don't know if there is a way to incorporated Drop box and a batch file but Help would be nice.

I also recommend Unison. It's dead simple to set up bi-directional syncing between two directories--local or remote.

Sounds like you're using Windows so I would suggest looking into its built-in Offline Files capabilities.

Check out this comment to a related Lifehacker article that suggests using Windows' "Offline Files" feature to quickly sync multiple files between computers.

Try Microsoft SyncToy - I use it to Sync network drives with a local folder. I think there is an option for auto-detection of changed files.

It will detect any files and folders that have been changed, added, etc, but doesn't run constantly in the background. –  martineau Aug 7 '12 at 16:38
