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.

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

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

When I run the following line:

For /f "tokens...
It replies that
The system cannot find the file specified

I assume this is what you were thinking, and thats why you had me do the dir/b

I got that to go away. I had a typo, sorry. Now there is no error, but it's not re-naming the file.

I got it...

YOU ROCK!!
