command like %systemdrive% for CDROM

[4johnny67]

Hi,

Is there a command like %systemdrive% but for "Cd-rom drive"?

In one of my batch files I hard-coded D: to specify my CD-Rom drive but I would rather not since other systems will not have D: as their Cd-Rom drive.

Is there a way to tell the system to look at the CD-ROM Drive and not just a hard-coded drive letter?

thanks

If you have not already done so, try %CDROM%

You can also search for cdrom in the thread titles. You'll like the results.

Inside a batch file you can use the %CD% variable for the current working directory. The %CD% variable isnt sugesting CDROM, it's short for Current Directory.

The %CDROM% variable works only during the installation phase, if I recall correctly.

The %CD% variable only exists in XP and above I believe. What I use in my batch files is the %~dp0 command. Like this:

SET MAINDIR=%~dp0

ECHO %MAINDIR%

To launch a file in the same directory as the batch file use:

%~dp0SETUP.EXE

You can also call a file in a relative subdirectory:

%~dp0FIREFOX\SETUP.EXE

Notice the lack of a backslash after %~dp0. %~dp0\SETUP.EXE is incorrect because %~dp0 includes the trailing backslash (although if you put it in on accident it still seems to work).

Hey

Check out this post.

Here it is shown how to make a permanent variable for your CD drive

[Martin Zugec]

This (working on XP Pro) will create variable strCdRom with drive letter... If you have more cdrom drives, I can create filter for cdrom name/media loaded

for /f "usebackq delims== tokens=1,2" %i IN (`wmic cdrom get drive /value`) DO set strCdRom=%j
