I need to look in a folder and rename a randomly named file with the extension .ls to temp.ls It will be the only .ls file in the folder. I then want to execute a program that will encode the file. It will change the file name to temp.tp. I then want to change the file name back to the original name with the .tp file extension. I need help with the file name manipulation. Please help! Mark.

@echo off > c:\files\my.ls setLocal EnableDelayedExpansion pushd c:\files for /f "tokens=* delims= " %%a in ('dir/b *.ls') do ( set FN=%%~Na ) echo ren !FN!.ls temp.ls echo someprog.exe temp.ls echo ren temp.tp !FN!.tp ===================================== If at first you don't succeed, you're about average. M2

I must be doing something wrong. My file is stored in c:\fanuc\temp The line for /f.... isn't taking the file name and putting it into !FN!.

@echo off setLocal EnableDelayedExpansion pushd c:\fanuc\temp for /f "tokens=* delims= " %%a in ('dir/b *.ls') do ( set FN=%%~Na ) echo ren !FN!.ls temp.ls echo someprog.exe temp.ls echo ren temp.tp !FN!.tp ===================================== If at first you don't succeed, you're about average.

Thats what I have. No luck...

do this and post result: dir/b *.ls ===================================== If at first you don't succeed, you're about average. M2

Under the C:\ nothing is there. I have the file in c:\fanuc\temp. If I do the dir there laser_1.ls displays.
