About
Filenames
Following is a complete list of acceptable charac-
ters for filenames:
Uppercase letters A through
Z
Lowercase letters a through z
Decimal digits
0-9
Symbols$&#
Yo'()@^
{
}
!-
When creating filenames and subdirectory names,
do not use more than eight characters. MS-DOS
ignores any characters after the eighth. For exam-
ple, MS-DOS regards both Accounts1 and Ac-
counts2 as Accounts. If you save both files,
MS-
DOS writes over the first file with the second, de-
stroying the first file. Also, MS-DOS does not distin-
guish between upper and lowercase letters.
Other than the ones listed above, you cannot use
symbols in filenames. There are also a few special
words (MS-DOS device names) that you cannot
use. These are:
aux coml com2
COm3
con Iptl
lpt2 COm4
lpt3 nul Prn
Filename Extensions
Any filename can contain an extension, which fur-
ther identifies the file. An extension appears at the
end of a filename, preceded by a period. You can
not assign an extension to a subdirectory name.
Extensions can have up to three characters and
can include the same characters allowed in
filenames.
