Hello Bit-Tech I'm having a bit of trouble finding an Auto-Sync tool that will work portably. Currently, I have a Dropbox script that always syncs dropbox when I plug my USB drive into a computer, but I'm looking to move past that a bit. As of right now, I work on 6 Workstations: Personal Desktop (Windows 7, D Drive) Personal Laptop (Ubuntu) Work Location 1 Desktop (XP, S Drive) Work Locations 2 Desktop (XP, L and U Drive) School Location 1 (Windows 7, U Drive) School Location 2 (Windows 7, U Drive) I'm wondering if there exists any tool out there that works on a USB, and can intelligently know "which" device it is plugged into, and Syncronize folders from that computer. I imagine there would be problems with understanding which U drive is which on the last 3 computers. Anyone aware of any portable utilities out there? If I have to, I'd settle for a 1 click utility. Thanks, Bit Tech.
