You can use wildcards to rename groups of files. For example, to
change just the extensions of all files on drive B with the extension

.NEW to .OLD, type the following and press 

Enter:

REN B:*.NEW *.OLD

To 

rename all files that begin with the same five characters

“MEMOS” but end with one varying character, type the following

and press 

Enter:

REN MEMOS? MEMOS?.OLD

See your MS-DOS Reference Manual for more information on the

RENAME command.

You can delete files you no longer need with the DEL (delete)

command. For example, to delete REPORT.AUG from drive B, type

the following and press 

Enter:

DEL B:REPORT.AUG

To delete the file WRENCHES from drive B, type the following and
press 

Enter:

DEL B:WRENCHES

You 

can use wildcards to delete groups of files. For example, to delete

all files on the diskette in drive A, you could type the following and

press 

Enter:

DEL A:*.*

Because deleting all files is a somewhat drastic operation, MS-DOS

prompts you to confirm your intentions when you use the *.*

wildcard combination with the DEL command.

A synonym for DEL is ERASE. Thus, you could substitute ERASE
for DEL in any of the preceding examples.
