This freeware device driver replaces the Microsoft CDFS.VXD (Compact Disc File System) in the subdirectory c:windowssystemiosubsys. Go to this directory and rename CDFS.VXD to something else. Then download and unzip the files. The cda files, appearing as WAVs, can be opened from CD in a wave editor and otherwise treated as WAV files. The best part, of course, is that you can use any WAV to mp3 converter to convert the cda file directly from the audio CD to mp3 (or other compressed format) without having first to extract it to hard disk. Saves a lot of space on hard disk and makes the conversion quicker. This driver will work with some drives, but not others.
When you open a CD after this replacement driver is installed, you will see two subdirectories on the disc in addition to the audio tracks. These directories are Mono and Stereo. Under each directory, you will see three additional directories, 11025HZ, 22050HK and 44100HZ. Opening these directories reveals the WAV files with the usual Windows WAV icons. Right click on one of the WAVs and choose Properties. If the file properties box shows the preview tab, then the drive is supported by this driver. If only the general tab is showin. If only the genis not capable of working with the new driver.
