Rules for 8.3-compliant filenames
The following criteria must be met for an '8.3-compliant' file or directory name:
1) The filename must be composed of all uppercase letters.
2) Any combination of letters (A-Z) and/or numbers (0-9) must be used.
3) The following special characters may be used:
$ Dollar sign
% Percent sign
' Apostrophe
' Opening single quotation mark
- Hyphen
@ At sign
{ Left brace
} Right brace
~ Tilde
! Exclamation point
# Number sign
( Opening parenthesis
) Closing parenthesis
& Ampersand
_ Underscore
^ Caret
NOTE: When a file or sub-directory is named in Windows 95, the system creates a primary filename, which can be a long filename, and an MS-DOS '8.3-compliant' alias. If the file or sub-directory name is already '8.3-compliant', then only one directory entry is used.
