List of disks, CD-ROM drives, USBs and other disk functions for LISP.

Using the Wbem system API, you can use LISP to detect the list of disk drives in Windows, the list of CD drives (including loaded media), removable USB drives, connected network drives, etc.

You can download the "CDROMs" function library from Download. Load it using APPLOAD. The individual functions return a list of discs and their properties in List form. You can then call the individual LISP functions as follows:

;(CDRoms) - list of CD-ROMs - e.g. ("D:" "E:") ;(USBs) - list of USBs - e.g. ("F:" "H:") ;(CDRomM) - list of CD-ROMs with media status - e.g. (("D:" . "loaded")("E:" . "empty")) ;(AllDisks) - list of all disks - e.g.: ; (("C:" . "localHD")("D:" . "CD-ROM")("F:" . "removable")("X:" . "network"))

Example:

Note: these functions are not supported in AutoCAD LT
