How to set multiple line command output in different variables? (Batch)

Question

I want to set the command outpus (multiple lines) as variables, depending on how many lines there are. First I want to export all accessable drives on the computer to a txt file:

    wmic logicaldisk get name>drivesvar.txt

Then read out these lines again and set the different drives as variables.

I tried alot witf for /f commands, but it didnt work so far. Would be glad, if someone could help me ! Thank you in advance.

Somehow this feels more at home over at SuperUser than here, but I may be wrong. — Shark

@Shark this is nicely in the scope of programming. (Well - one could argue that the question is not on topic here, because OP didn't show us his failing code) — Stephan

@Shark: Superuser: "Is your question about computer software or computer hardware?" Stackoverflow: "Is your question about programming?" - As I read this question, it's about programming (let us not discuss the difference between "programming" and "scripting" here), not about software or hardware. — Stephan

The concept you are looking for is called array. See: this post — Aacini

@Stephan fair enough, thanks for the correction; I'll try to do better in the future. — Shark

you don't need a file:

@echo off
setlocal enabledelayedexpansion
set i=0
for /f "tokens=2 delims=:=" %%a in ('wmic logicaldisk get name /value ') do (
  set /a i+=1
  set drive[!i!]=%%a
)
set drive

If you need the colon, just add it at set drive[!i!]=%%a: (I removed it (as one of several methods) to get rid of the unusual wmic line endings)
