Script package for file name prefix

Question

I am trying to rename files in a batch script as follows:

rename %FOLDER%\* 1-* 

but when you run the script, it overwrites the first two characters of the original names with the prefix "1-" instead of adding it to the beginning of the file names. How can I get around this?

Answer 1

Rename will simply rename the file, you will need to call the file name as a variable after the prefix. The following shows how it works.

 cd %folder% for %%a in (*) do rename "%%a" "1-%%a" 

Answer 2

try this as a starting point

 @echo off for %%a in (%folder%\*) do ( echo ren "%%~fa" "1-%%~nxa" )
