A+: Internal Commands list

These commands of the Windows Command Prompt are built into CMD.EXE and do not need to load from an external file: DATE, TIME, COPY, DEL, ERASE, DIR, MD, MKDIR, CD, CHDIR, RD, RMDIR,  VER, VOL, SET, PROMPT, PATH, ECHO, CLS, HELP and TYPE. 

Command-prompt functions and utilities can be used to operate on a group of files with similar names by using one of the following wildcard symbols:

 ? replaces a single character, and you can use ??? to find any three characters, excluding two or four characters.

 * replaces a group of characters.
