In addition to the rules here, you'll find that for use in Excel, it is also
helpful to disallow [square brackets] and 'single quotes' from file names.

Hello

I am writing a version control macro and need it to identify whether
the file name entered by the user is valid as a file name. Can
anybody either:

a) provide some code that identifies whether a given text string is
allowable as a file name?

b) provide a list of all characters that are not allowable in file
names so that I can write such a piece of code myself.

Thanks

John
