CertiGuide to A+ (A+ 4 Real)  9  Chapter 1: What are Operating Systems and How Do They Work?       9  CDI System Commands

The Echo Command 1 The RMDir / RD Command

Both of these commands achieve the same goal, namely the removal of files from the hard drive. The del command (short for “delete”) is more widely used than erase, probably due to the fewer number of keystrokes required to type it. (All three commands are valid.)

Del accepts either a filename or a wildcard as the target for deletion, specified in the same style as the copy command. Be careful when using del with wildcards, as it is very easy to delete a large amount of files by mistake. Del does not prompt for confirmation, except in one specific circumstance – when using the *.* wildcard, which pattern matches every file. Prior to DOS Version 3, even this special circumstance did not exist.
