Calculation for valid Windows File path

[Tissot]

Hello guys

What is the best approach for evaluating a Path so that it’s a valid Windows file name?

The following character are not allowed:

/  : * ? " < > |

Cheers

Allright, I sorted it with PatternCount() function.

Thanks

IsEmpty ( Filter ( text ; characters ) ) is better suited for testing multiple characters.
