I was looking for help on copying data from Dir.Internal to an SD Card using the ExternalStorage class and noticed a few other people couldn't quite get to grips with it either. So for them here's an example, which works for me. Took me a while to get something to work, but got there eventually. Works for me anyway.

B4X:
Try
   Storage.SelectDir(False)
   Wait For Storage_ExternalFolderAvailable
   Dim lFileName As String="test.db"
   Dim InputStream1 As InputStream
   InputStream1 = File.OpenInput(File.Dirinternal, lFileName)
   Dim lFile As ExternalFile
   lFile=Storage.CreateNewFile(Storage.root,lFileName)
   Dim outputstream1 As OutputStream
   outputstream1= Storage.OpenOutputstream(lFile)
   File.copy2(InputStream1,outputstream1)
   InputStream1.Close
   outputstream1.close
   Msgbox2("Database copied. File Name: "&lFileName,"Info","OK","","",Null)
Catch
   Log(LastException)
End Try
Remember you'll need the ExternalStorage class. You can get it by searching the forum.
