DOS 3.3 and Norton Commander (pre-Semantec).
Norton Commander was a nice file manager I still use Norton File Manager that I stripped from NT Tools, the only problem with it is the 4GB barrier. When ever the free drive space gets close to an increment of 4GB, it thinks it's running out of space and won't allow you to copy files on to that drive until you copy a few files to it which breaks the 4GB increment.
