File System CFN3 File System
The root directory is called / (slash) on the CFN3 application and directory names are
separated by a /. (On NT or MS-DOS systems \ [a backslash] is used instead of /.) So, for
example, the filename /BIN/TREE.BIN refers to the file TREE.BIN in the directory BIN
under the root directory (/).
Figure 17-1 shows this directory structure.

There are two special directory names: . (dot) and .. (dot dot). The . (dot) represents the current
directory, and .. (dot dot) represents the parent directory (one level up) of the current directory.
The current directory is the directory you are in at the present time. Whenever the CFN3
application is turned on, one directory is always the current directory (just as whenever you are
inside a house, you are always in one room or another).
You can give a full pathname or relative pathname (using the dots and slash) to name a file that
is not in the current directory. For example, ../FRAMOS.BIN names the file FRAMOS.BIN in
the parent of the current directory, and /FRAMOS.BIN names the file FRAMOS.BIN in the
root directory.
Disk Drive Names
Disk drives are referred to by drive letter. The disk drive names are as follows:
Name Description
A: First floppy disk drive
B: Second floppy disk drive (if present)
C: PC’s hard disk drive
D: CD-ROM drive
P: SC3 root directory and the default SC III drive
R: RAM drive
Each drive has its own file system. This means there is a root directory on each drive. The
[P:*] represents your site controller.
