Sorry if this can be found elsewhere on the forum, but after a half dozen searches using VARIOUS phrases I couldn't find the answer.

What I need help with is how to find a specific "flag" file that resides in the root directory of a drive. It's probable that the drive letter will change which is why I need to be able to iterate through the list of drives on the machine.

Pseudo code would be:

Code: [Select]for each DRIVELETTER in E: - Z:
if exists flag_file.txt
set X = driveletter
return
end
end

do something with X

Thanks for your help.

coding is base on your pseudocode:

Code: [Select]@echo off

for %%a in (e F g h i j k l m n o p q r s t u v w x y z) do (
if exist %%a:\flag_file.txt (
set x=%%a:\
goto:x
)
)
if not defined x echo flag_file.txt Not Found & goto:EOF
:x
echo First Found Drive=%x%
