DRIVE [letter$]
letter$ - drive such as “A:” or “C:” (optional; omit to list drives)
A: is the RAM disk. C: is the SD card slot. D: and later are USB volumes when present. B: is an internal package mount and is never listed. A FAT volume’s label is shown in quotes, e.g. `D: USB “MYSTICK”`, and in the FILES pane captions. Use EJECT to unmount a stick safely before pulling it.
Z: is the network drive set up with OPTION NETWORK DRIVE, an SMB share mounted over the network. It is listed as `Z: SMB \\host\share` and shows `(not connected)` until the first Z: access connects it; listing drives does not connect. EJECT “Z:” drops the connection.
