Batch file to list all files and save one of them in variable in a loop

Question

I was looking for a batch file, that saves one of listed files as variable, then proceeds to get some information about it and then set him as already listed, and then list every other file until there are none left. Important is to make %FILE% as single file (ex.: C:\folder\file.ext) I was trying this:

@echo off
:loop
for %%x in (%dir%\*) do set FILE=%%x
if %FILE%=%alreadyusedfile% goto loop
goto scan

:scan
echo Now scanning %FILE%
(do some things here)
set alreadyusedfile=%alreadyusedfile% %FILE%
goto loop

But seems it doesn't work. Any ideas?

You need to process the files within the loop which you have two options.

Using the CALL command to make your code work like a function.

@echo off
for %%x in (%dir%\*) do call :scan "%%x"
goto :eof

:scan
echo Now scanning "%~1"
(do some things here)
Goto :eof

Or do everything within the FOR construct.

@echo off
for %%x in (%dir%\*) do (
    echo Now scanning %%x
    do some things here
)

@rifteyy they both work. If the second one does not work for you then you changed something. – Squashman May 21 '21 at 11:49

@rifteyy because you haven't shown us all the code you are attempting to use I can't even guess what might be wrong with how you attempted to implement the second set of code. – Squashman May 21 '21 at 14:04
