Batch file to create a folder in every removable device

Solution 1:

Why is this not working?

'wmic volume get driveLetter^ where drivertype=2

You have several errors in the above wmic command:

• drivertype should be drivetype.
• There is a missing trailing '.
• The `^ is not needed.
• The where should come before the get.
• Not all disk volumes have drive letters (but logical disks do).

Use the following batch file:

@echo off
setlocal
for /f "skip=1 tokens=1,2" %%d in ('wmic logicaldisk get caption^, drivetype') do (
  if [%%e]==[2] echo mkdir %%d\test
  )
endlocal

Notes:

• Remove the echo before mkdir when you have tested the batch file.
• You may need to do something with drive type 3 as well.

• I have a removable drive of type 3. In the below output C: is a fixed hard disk, D: is my CD ROM drive, E: is a removable USB stick and F: is a removable external USB drive.

  F:\test>wmic logicaldisk get deviceid, drivetype
  DeviceID  DriveType
  C:        3
  D:        5
  E:        2
  F:        3
