Windows – Creating a folder from first 5 characters of filename in a batch file

batch filecommand linewindows

Here's what I have:

C:\test\12345-test1.txt
C:\test\23456-test2.txt
C:\test\44444-test3.doc


I would like to have the script read the first 5 digits from the file, create a folder with those digits, and include the letter T before it.

The result after running should be like this:

C:\test\T12345\12345-test1.txt
C:\test\T23456\23456-test2.txt
C:\test\T44444\44444-test3.doc


Currently, I have this, which does the function; I just can't figure out where to put the SET command to extract the 5 characters.

@echo off
for %%a in (*.*) do (
md "T%%a" 2>nul
move "%%a" "T%%~a"
)


I think this needs to be added to choose only the first 5 characters:

set first5=%%a:~5,1%


Thoughts?

• @echo off

for /f %%a in ('dir /a-d /b') do (
if not "%%~dpnxa"=="%~dpnx0" call :func "%%~a"
)

goto :EOF

:func
set file=%~1
set dir=%file:~0,5%
md "T%dir%" 2>nul
move "%file%" "T%dir%"
goto :EOF


This will process files (= no dirs) in the working directory. I also added a check to prevent the script from moving the batch file itself in case it happens to be located in the wd.
