   Dim files As List

   files.Sort(True)
   For i = files.Size - 1 To 0 step -1
      If File.IsDirectory(IdePath, files.Get(i)) Then
         Log(files.Get(i))
         files.RemoveAt(i)
      End If

File.ListFiles returns a read-only list. You can't remove items from it.
I believe that sorting will also fail (it may seem to work because the files are already sorted).

Thanks Erel, I had totally overlooked that.

Note that you can easily copy a list with:

Dim List2 As List
List2.Initialize
List2.AddAll(List1)

The new list will not be readonly.
