Regex how to add ignore case switch

Folder Formats add wildcard path format

wildcard path: temp
not match
d:\Temp
d:\111\TEMP
c:\windows\tEmp

I don't think case sensitivity is the issue, it's just that the pattern doesn't match. "temp" won't match anything other than "temp". You'd need to use wildcards to make it match more, e.g. "*\temp" should match all of your examples.
