I took the idea from this forum https://stackoverflow.com/questions/...-under-windows

We can use regular expressions to check if a given file name is valid.




///
/// Validates a filename for incorrect characters
///
///
///
public boolean checkFileName(Filename _fileName)
{
var bad = System.IO.Path::GetInvalidFileNameChars();
var esc = System.Text.RegularExpressions.Regex::Escape(new System.String(bad));
var exp = new System.Text.RegularExpressions.Regex("[" + esc + "]");

if (exp.IsMatch(_fileName))
{
return checkFailed(strFmt("@SYS339524")); // The specified filename is invalid.
}
return true;
}
