2.0 FILE TRANSFER
DISKFILER 2 transfers one or several files from the RAM memory
of the Z88 to the disk or from the disk to the RAM memory of the
Z88. In order to make full use of all of the facilities provided by
DISKFILER 2, it is necessary to understand the way that files,
directories and disks are implemented in both the PC-compatible
disk and the Z88.
2.1 The Filing System
The filing system on both the Z88 and disk can be thought of in
much the same way as a filing cabinet. Typically, a filing cabinet
would consist of a number of drawers, each one containing a
number of folders. Each folder may contain several different letters.
In order to extract a particular letter from the filing cabinet, the
user has to specify which folder in which drawer contains the
letter. On a Z88, the drawers are equivalent to the individual RAM
cartridges, called devices. The folders are equivalent to directories
and the letters are equivalent to files. Thus, to extract a particular
file, the user must specify the device (drawer); the directory (folder)
and the filename (letter). The devices are named as follows:
: RAM.0 The internal memory of the Z88
: RAM. I The RAM cartridge in slot l of the Z88
: RAM.2 The RAM cartridge in slot 2 of the Z88
:RAM.3 The RAM cartridge in slot 3 of the Z88
The directory names are chosen by the user and are made up of up
to 12 characters on the 288, but only 8 on the disk.
Thus the full specification of the file "PART1.DOC" in the directory
"MANUAL" held on the RAM cartridge in slot 1 would be:-
:RAM. 1/MANUAL/PART1.DOC
It would be inconvenient and time consuming if every time the user
wished to specify a file, it was also necessary to specify the
directory and the device. To overcome this requirement, both the
Z88 Filer and DISKFILER 2 allow the user to select the device and
the directory that he wishes to use in the Z88 and also the disk
directory. These are called the Default Device and the Default
Directories respectively.
