Thanks. I tried them, it works for most of those characters except "*" and "?".
Does regular expression work in file names in windows? e.g. I have a machine-generated file named "021706 matrix#1479 @50.csv", of which "1479" is kinda random. Will I be able to match "1479" with some sort of "wild card" chars?
