in thread Regular expression to check for invalid file name characters

I was trying to make the application as user friendly as possible. Therefore I thought it worthwhile checking that all the characters supplied could be used (rather than getting a system error message which may not be that good to work with).
Also, I should have said that I am working on Windows - hence the list of invalid characters I gave in the subroutine.

    I understand. And I think it is a good thing to check if the filenames are supplied by (especially novice) users.

    If they enter a filename "temp\fred.txt", you could end creating fred.txt in the temp subdirectory rather than their expectation on a file called temp\fred.txt in \.
