The final version of the MSCDEX program was 2.25,[citation needed] included with Windows 95 and used when creating bootable floppy disks with CD-ROM support.

[8] Using EMS with a page frame, NWCDEX can reduce its footprint even down to a few bytes in conventional memory.

[8][12] An alternative solution, but less flexible, some versions of DR-DOS offer to delay the installation of a driver in CONFIG.SYS until after the DOS data segment relocation via INSTALLLAST.

In 1998, Caldera provided a DRFAT32 driver for DR-DOS to dynamically mount and unmount FAT32 volumes on DOS versions otherwise not natively supporting FAT32.

DRFAT32 uses a variation and extension of the CDEX API in order to achieve this and work with older DOS versions.
