Adding prefix to all filenames in folder

Adding a prefix to all filenames in a directory from Windows Command Prompt. Only to filenames, not to folder names as well:


FOR /F "TOKENS=*" %G IN ('DIR /B /A-D') DO REN "%G" "PREFIX%G"

Code for .BAT file:


@ECHO OFF
FOR /F "TOKENS=*" %%G IN ('DIR /B /A-D') DO (
	REN "%%G" "PREFIX%%G"
)

Note: enter your prefix instead of PREFIX.

Adding prefix only to filenames of specific type

Prefixing only .htm and .jpg files for example:


FOR /F "TOKENS=*" %G IN ('DIR /B /A-D *.htm *.jpg') DO REN "%G" "PREFIX%G"

Code for .BAT file:


@ECHO OFF
FOR /F "TOKENS=*" %%G IN ('DIR /B /A-D *.htm *.jpg') DO (
	REN "%%G" "PREFIX%%G"
)

Note: enter your prefix instead of PREFIX.
