16.3 microSD File System
The microSD Memory Card slot uses the PC-compatible FAT32 File System. This means that a
PC, with a microSD-compatible card reader, can read files that have been written by the
XL4/XL4 Prime OCS and can write files that can be read by the XL4/XL4 Prime OCS.
However, the XL4/XL4 Prime OCS does not support long filenames, but instead implements
the 8.3 filename format. This means that all file and directory names must consist of up to
eight (8) characters, followed by an optional dot, and an optional extension with up to three
(3) characters.
Directories and sub-directories can be nested up to 16 levels deep as long as each pathname
string does not exceed 147 characters.
16.4 Using the Removable Media Manager
The Removable Media Manager is an interactive XL4/XL4 Prime OCS screen that performs the
following functions:
a.
Display number of total and free K bytes
b.

c.

d.

e.

The Removable Media Manager can be accessed via the System Menu or by using Cscape to
