What is 4DOS
4DOS is a replacement for command.com, the command processor included in most versions of DOS, far more powerful and flexible, however, than this feeble program. After many years of being commercially successful, 4DOS is now made available for free by its author, Rex Conn of JP Software, at their Downloads Page. It's officially unsupported, though the support forum will generally try to answer your questions.
Here is a text quoted from the BMTmicro website that describes some 4DOS features :
If you've ever been frustrated by the limitations of standard "DOS commands", then 4DOS is the one command line tool you truly need. By adding a wide array of features that DOS omitted, 4DOS makes the command line easy to use, giving you more power and flexibility than you ever imagined. 4DOS replaces the DOS command processor, COMMAND.COM -- the brains behind your "C:\>" prompt.
4DOS adds features such as shorthand "aliases" for commonly used commands, a pop-up directory history window, and the ability to copy, move, delete, or list multiple files with a single command. Simple command-line editing, history, and recall eliminates extra keystrokes, and the FIND command can quickly locate files or text within a file anywhere on your system.
Batch file users will be amazed at the power and speed 4DOS adds to the DOS batch processor with sophisticated new batch commands. Enhanced batch files can fix annoying quirks, leaving a smooth, elegant environment designed to meet your needs and preferences.
