On my portable hard drive I set icons for almost every organized folder. All these icons are located in an Icons folder located on the root directory of the same hard drive.

When I change the drive letter of the hard drive (well I don't, windows does automatically sometimes) these icons are lost. So far this hard drive is assigned to F:

While it's not a problem now, it may becomes a problem if I upgrade my computer or get a new one and the F: Drive is already taken up for something else. It's also annoying on networks where F: is mapped to a network drive.
