we would recommend to be more specific on the samples (as we expect also the paths)
arrOrderedFullPaths | String Array =
(From fi in new DirectoryInfo("YourFolderPath").GetFiles()
Let nas = System.Text.RegularExpressions.Regex.Match(fi.Name, \d+).Value
Let nai = CInt(nas)
Order By nai
Select f = fi.FullName).ToArray
