bat file only runs first lines command

Question

I want a .bat script to run on boot which will automatically increase the hard disk space.

diskpart
select volume 1
extend
exit

However that in a .bat file just runs the first command only. I can only get it working if I manually paste it into command prompt.

I have also tried with adding CALL before each command which did not work.

CALL diskpart
CALL select volume 1
CALL extend
CALL exit

how did you manage to assume that completely made-up commands work? I think you should do a tutorial on computers before you start scripting ... — specializt, Sep 25 '15 at 10:37

Each line in a batch file represents a shell command or batch function. "select volume 1" is not a command that is recognized, it is text you wish to send to the running program. See how to pass input to .exe in batch file? to pass input to an executable, or find out if the executable supports scripting.

DiskPart does supports scripting. Put your script in a file, say "ExtendVolume1.txt":

select volume 1
extend
exit

Then run DiskPart:

diskpart /s ExtendVolume1.txt
