JSI Tip 8518. How can I convert a LFN to a SFN?

I have scripted CvtLFNSFN.bat to convert a LFN (Long File Name) to a SFN (Short File Name).

NOTE: LFN refers to the file name and extension, NOT to the folder path.

The syntax for using CvtLFNSFN.bat is:

CvtLFNSFN LFN SFN

Where LFN can be the LFN or the FQFN (Fully Qualified File Name), and SFN is a call directed environment variable that will contain the SFN.

NOTE: Neither the LFN nor the FQFN has to exist.

CvtLFNSFN.bat contains:

@echo offif {%2}=={} @echo Syntax: CvtLFNSFN LFN SFN&goto :EOFsetlocalset file=%~nx1@echo.>"%TEMP%%file%":loopfor /f "Tokens=1* Delims=" %%a in ('dir "%TEMP%%file%" /X^|find "%file%"') do ( set line=%%a)del /q "%TEMP%%file%"for /f "Tokens=1*" %%a in ('@echo %line:~36%') do ( set sfm=%%a)endlocal&set %2=%sfm%
