I haven't thoroughly tested this, but let's say your filename was in the %FILENAME variable... this will put the extension in the %FILE.EXT variable: Code: set %FILE.EXT $right(%FILENAME,$calc($len(%FILENAME)-$pos(%FILENAME,.,$count(%FILENAME,.))+1)) It will also work for file extension longer or shorter than 3 characters, and files that are like :"little.bown.happy.dog.gif" Hope that works for you Last edited by spling; 23/04/04 04:46 AM.
