The boot system identifies a file in flash ROM by the first four characters
of the file name. When a file is read from a memory card while a file
having a file name starting with the same four characters exists, the
existing file is deleted, then the new file is read into the flash memory. The
table below lists the file names and corresponding contents. The file
names are subject to change without notice.

An SRAM backup file on a memory card is given a name determined by
the size of the SRAM mounted on the CNC. When the size of the SRAM
is greater than or equal to 1 MB, multiple 512–KB backup files are
created.
