Fixed

FIXED: Changed in the file creation date to the substitution
DateTime.Now.ToString(CultureInfo.InvariantCulture)
.Replace(@"/", "-")
.Replace(":", "-")+".xml"
That cleared up the problem with the creation of files with different
regional settings.

ADD: Editing by double-clicking on the row

ADD: Close forms after press ESC

ADD: Added progressbar when working backup through the form
