Description

This plug-in will return every available CD-ROM drive on the user's machine one by one.

This plug-in requires NSIS 2.

Put EnumCDs.dll in the Plugins directory under the directory where you installed NSIS.

How To Use

To use it call EnumCDs::next with the /NOUNLOAD flag, and keep popping the results, the CD-ROM drive letters, one by one until the plug-in pushes "done". Then call EnumCDs::next once more without the /NOUNLOAD flag, pop the second "done" and you're done.

Example

again:
  EnumCDs::next /NOUNLOAD
  Pop $0
  StrCmp $0 "error" done
  DetailPrint $0
StrCmp $0 "done" done again
done:
  EnumCDs::next
  Pop $0
