6. FILE SYSTEM, cont'd.
File Types
A number of different types of files can be stored in the various parts
of the printer's memory. They can be divided into four main groups:
• Program Files
• Data Files
• Image Files
• Outline Font Files
Object files, fonts, bar codes and images are not treated as files by
the Fingerprint firmware.
File Names
The name of a file may consist of up to 30 characters including
extension, but possible restrictions imposed by the operating sys-
tem of the host should be considered if the file is to be transferred.
Refer to chapter 5.13 for a list of file names reserved for Intermec
Fingerprint utilities.
Listing Files
The files stored in the printer's memory can be listed by means of
the FILES statement. By default, the files stored in the current
directory will be listed. Optionally, another directory can be se-
lected by adding a reference to the FILES statement:
FILES lists all files in the current directory.
FILES "rom:" lists all files stored in EPROM and in any
inserted non DOS-formatted memory card.
FILES "ram:" lists all files stored in the printer's RAM
packages.
FILES "card1:" lists all files stored in any inserted DOS-
formatted memory card.
You can COPY a file to the standard OUT channel, where it will be
printed on the screen of the host, e.g.:
COPY " [device]filename ", "uart1:"
The FILELIST.PRG program also LISTs a line-orientated file to
the standard OUT channel:
• On your terminal, enter:
RUN "rom:FILELIST.PRG "
• The printer will respond by prompting you to enter the name of
the file to be listed:
Filename?
• Enter the filename, possibly preceded by a directory reference,
e.g.:
"rom:*.*".
