Hi @dragoni7 thanks for this PR! Please see https://github.com/dragoni7/Files/pull/1/files for suggested changes.

• Backup conversion should not be needed because Convert.ToInt32() calls int.Parse(string) internally.
• The exception you're trying to solve is from this line { "FormatDuration", input => TimeSpanToString(new TimeSpan(Convert.ToInt64(input)))}, (note the "ToInt64()" like in the stacktrace) so a try catch is also needed around DisplayFunction.Invoke()
