Choosing a file format
In some programs you’ll have the choice of saving the document in one of
several file formats.
A document’s file format refers to the way information within the document is
encoded. If a program cannot accurately interpret a document’s file format, it
may display the document incorrectly (as in the figure below).
When you save a document that you plan to use with another program, be
sure to save it in a file format that the other program can understand. (To find
out what file formats a program is able to open, import, and save, see the
documentation you received with the program.)
Naming files for use on both Macintosh and DOS computers
On DOS computers, filenames are limited to eight characters (plus a three-
letter suffix) and may not contain spaces. The rules for naming Macintosh
files are less restrictive. Therefore, when working on the Macintosh, it’s
possible to give a file a name that would be “illegal” on DOS computers.
