Adding prefix to all filenames in folder

Adding a prefix to all filenames in a directory by FOR command under Windows. Only to filenames, not to folder names as well. Batch file contents:

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

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

Note: enter your prefix instead of PREFIX.
