Get full path and long file name from short file name

Question

I have an nice console file manager (eXtreme by Senh Liu), it passes short path/filenames as variables to a menu.bat.

How can I generate a full folder name + long fi

Answer 1

This returns the full long pathname, but depends on:
A) there not being too many files in the tree (due to time taken)
B) there is only one of the target (long) filename in the tree.

@echo off
for /f "delims=" %%a in (' dir /b "%~1" ') do set "file=%%a"
for /f "delims=~" %%a in ("%~dp1") do cd /d "%%a*"
for /f "delims=" %%a in ('dir /b /s /a-d "%file%" ') do set "var=%%a"
echo "%var%"

When called with mybat "d:\MYPROG~1\SHELLS\zBackup\REFSTO~1.BAL"
it returned this:

"d:\MyPrograms\SHELLS\zBackup\RefsToMyData.bal"
