Dim DestinationPath As String

DestinationPath = File.Combine(File.DirRootExternal, "Pictures/MyApp")

If File.Exists(DestinationPath, "") == False Then
File.MakeDir(File.Combine(File.DirRootExternal, "Pictures"), "MyApp")
End If

File.Copy(File.DirInternalCache, SourceFile, File.Combine(File.DirRootExternal, "Pictures/MyApp"), DestinationFile)

[B4X] Features that Erel recommends to avoid​

• File.DirDefaultExternal -> RuntimePermissions.GetSafeDirDefaultExternal
  Truth is that you shouldn't use both of them and use XUI.DefaultFolder instead.
