I need to get list of all files supported by some libary (images) in specified directory and all subderictories. Root directory of drive might be chosen and in this case I want to skip system folders like “Windows” and “AppData” (some other?).

For such task I can use Directory.GetFiles() but problem is – it will stop after getting any exception. In this case I need to just ignore noncritical exceptions and skip folders that cause this exception.

This code looks resonable to me. But I want to make sure that it done right.

Please tell me if it should be changed somehow.

public static List<string> FindSupportedFiles(string root) {     Queue<string> folders = new Queue<string>();     List<string> files = new List<string>();      folders.Enqueue(root);     while (folders.Count != 0)     {         string currentFolder = folders.Dequeue();          if (currentFolder.Contains(":/Windows/")) currentFolder = folders.Dequeue();         if (currentFolder.Contains(":/Users/") &&             currentFolder.Contains("/AppData/")) currentFolder = folders.Dequeue();          string[] filesInCurrent = null;         string[] foldersInCurrent = null;         try         {             filesInCurrent = Directory.GetFiles(currentFolder, "*.*");             foldersInCurrent = Directory.GetDirectories(currentFolder);         }         // Ignore this exceptions         catch (UnauthorizedAccessException) { }         catch (PathTooLongException) { }         catch (DirectoryNotFoundException) { }          foreach (string f in filesInCurrent)             if (SomeLib.IsSupported(f)) files.Add(f);               foreach (string _current in foldersInCurrent)             folders.Enqueue(_current);     }     return files; }
