Using the Office
Each file and file folder is identified by a name. By
assigning a name that describes the contents of the
file or folder, you can organize your work more easily.
The computer places some restrictions on the names you
can use. File and folder naming restrictions are:
o All names for objects of the same type within
a particular object or folder must be
different. For example, you cannot have two
files named example in the practice file
folder. However, you can have two files
named example in two different file folders
in your Filecabinet.
o You can use upper- or lowercase letters in
file names, but keep in mind that uppercase
and lowercase are not the same to the UNIX
PC. For example, myfile, Myfile, and MYFILE
are three different file names.
o A file or folder name can be from 1 to 14
characters long. For some applications, the
maximum length of a file name used by the
application is shorter than this. Your
application manuals tell you the maximum
length for file names and you will not be
allowed to assign a longer name to this type
of file.
o You can use letters, numbers, periods (.),
hyphens (-), and underscores (_) in file
names. You should not use other symbols, and
you should not use a period as the first
character in a name.
Some of the
application~
you use may add some
characters, such as .hlp or :F, to the end of
the names of their files. You will not see
these additional characters in the folder
displays, and you do not usually need to be
concerned about them. Appendix B contains a
list of the added characters used by the
Office software for special files. See your
application manuals for information on the
special suffixes that each application can
use.
