Linux is preferable, but that would be nice if there's a Windows solution :)
I have two USB HDDs, and each has category folders: e.g. "Music" and "Video" - kinda archive. Later, when they're full, i will add more devices.
Is there a way to join the two dir trees (from different devices) into one virtual filesystem? So that i can access its root, and see all files joined into one tree?
