All About Files
The convenience of the HP 95LX is impressive. But, like any other Information
Manager, you must use it wisely and efficiently to gain its power and convenience.
To use it best, you must start by understanding its filing system.
Naming Files
The basic unit of organization on the Palmtop—as on any PC—is the file. Files
have different structures and formats depending on what kind of data they contain
and what programs use them. The HP 95LX uses the filename extension—the
three character suffix of a filename that follows the period (.)—to classify the
various kinds of files its built-in programs use. Here’s a list of these file extensions:
-ABK:
BAT:
«CHF:
«COM:
CTF:
DAT:
= DCF:
» ENV:
«EGN:
«EXE:
