Pathname
The name of the directory combined with the names of one or
more subdirectories is called a pathname. Volume names and
subdirectory names are preceded by a slash, “1”. (Note that some
applications add the slash for you.) For example, you could have
a volume named
/MY
.
DISK
and a file called
NY. FILE
on the
root directory of that disk. To access that file, you would use the
pathname
/MY.DISK/MY.FILE.
You could also have a file
JUL
.
AUG
in a subdirectory (folder) called
PHONE
on a disk called
/BILLS.
To access that file, you would use the pathname
/BILLS/PHONE/JUL DEC.

ProDOS Directory Structure
Now when an application asks you for the pathname of a file,
you’ll have a basic understanding of what it expects.
System Files
A system file is a ProDOS file that starts an application.
Typically, these files have the suffix
.
SYSTEM
(e.g.
/APLWORKS
.
SYSTEM, /ACCOUNT. SYSTEM
[see above], etc.). When
you boot ProDOS, it runs the first system file listed in its
directory. So, if BASIC.SYSTEM is the first system file on your
ProDOS boot disk, ProDOS will boot and then put you in BASIC.
