The .IMD files need to b converted into a form that CMIOS9 can read. Try this to convert the .IMD files for use with CMIOS -

1. place the .IMD files in the same directory as ImageDisk 1.18.

2. Use the following command to convert the .IMD files to .BIN files: imdu FILENAME.IMD /B FILENAME.BIN
This will generate a binary file.

3. Now move the FILENAME.BIN to the CMIOS9 directory so it's with the cmios9.exe file. 

4. Open the .BIN file using cmios9 with the following command: cmios9 -q 1 FILENAME.BIN

5. You're now working within cmios9. The dir command will list all files that are on the 'floppy'.

6. Extract all the .VC files as .WAV files (note they will still have the .VC extension): vc2wav *

7. Use the following command to extract the other files: export FILE.EXT
