Total Commander is a file manager for Windows, a program like Windows Explorer to copy, move or delete files. However, it can do much more than Explorer, e.g. pack and unpack files, access ftp servers, compare files by content, etc.
Total Commander has internal unpackers for ZIP, ARJ, LZH, TAR, GZ,CAB, RAR and ACE formats and also additional packers can be added as plugins. The build-in FTP client supports most public FTP servers and is able to resume aborted downloads, handle archives and can send files directly from one remote server to another. Total Commander has a lot of nice features that will help in file handling tasks as well.
