Dont think its good for my situationYou can use the File methods to list them by yourself.
You may have a look at the ClassWildcards to get some inspiration.
For external sdcards you need to use the StorageAccessFramework. Note that the Classwildcard does not work on external sdcards.
You need to build your own solution.
Sub findFiles(path As String, extn As String, result As List) Dim files As List = File.ListFiles(path) If (files.IsInitialized) Then For Each f As String In files If (File.IsDirectory(path, f)) Then findFiles(path & "/" & f, extn, result) Else If (f.EndsWith(extn)) Then result.Add(path.Replace(File.DirRootExternal, "") & "/" & f) End If End If Next End If End Sub
