Total Commander is, in few words, an enhanced version of Norton Commander for Windows (or Midnight Commander in Linux)... It even keeps the same window aspect and the same functions assigned to the same keys! Everyone that used NC knows what I'm talking about: two panels, smart hotkeys and combinations, easy to use, simple and effective, great for slow PCs.
Windows Commander is a graphical interface that lets you in a easy way administer all your files and directories, from there you can do simple task as copy, transfer, delete, rename, but you can also connect to your network resources, share directories, pack archives and encode or decode files.
