A Brief ProDOS Tutorial
This is a brief explanation of the Pro Disk Operating
S ystem, ProDOS
this information and more is included in your Apple Owner's
Guide, but we have provided it here for your convenience.

Operating System

ProDOS is one of several operating systems for the Apple.
Others include DOS 3.3 and Pascal. Operating systems, as defined
in the Apple Owner's Guides, are programs that control how
information is loaded into memory, how the computer handles
the information, how the information is stored on a disk, and
how the computer communicates with the printer and other
peripherals.

Naming Volumes

ProDOS must have a way to locate which disk (often called
"volume") you want to access. Instead of typing in the location
of the disk as in DOS 3.3 (ex: S6,DI), you simply type in the name
of the disk (the volume name). Some rules for volume names
are
1) Name can include letters, numbers, or periods but not
spaces.
2) Name must begin with a letter.
3) Name can be up to 15 characters long.
These rules also hold true for subdirectory names.

Root Directory and Subdirectory

The main directory of the volume is called the root directory.
The root directory uses the same name as your disk.
Subdirectories are ProDOS' way of organizing information on a
disk.
Think of the root directory as a file drawer and the subdirectories
as folders within the drawer. You can
1) Put files directly into the root directory like putting
documents straight into the file drawer.
