JSI Tip 8138. How can I determine a computers hard disk letters in a batch?


Microsoft Windows NT-based operating systems assign an administrative share to every hard disk partition.

Using the RMTShare.exe public domain software, I have scripted DriveLetters.bat to return a local or remote computer's hard disk letters.

The syntax for using DriveLetters.bat is:

DriveLetters ServerName

Where ServerName is the NetBIOS name of the local or remote computer.

The output (DriveLetter:) is displayed on the console, but you can use it in a script:

for /f "Tokens=*" %%d in ('DriveLetters ServerName') do (
 set drive=%%d
 call :SomeRoutine
)
DriveLetters.bat contains:
@echo off
If \{%1\}==\{\} @echo Syntax: DriveLetters ServerName&goto :EOF
setlocal
set srv=%1
set srv=\\%srv:\=%
for /f "Tokens=1,2" %%a in ('rmtshare %srv%^|findstr /c:"$"') do (
 call :fnd %%a %%b
)
endlocal
goto :EOF
:fnd
set p1=%1
set p2=%2
if /i "%p1:~0,1%" NEQ "%p2:~0,1%" goto :EOF
if "%p1:~1,1%" NEQ "$" goto :EOF
if "%p2:~1,2%" NEQ ":\" goto :EOF
@echo %p2:~0,2%
NOTE: See Computers.bat.
