It is an account manager and you can create/delete/export/import accounts using it. Exporting and Importing have two options. Either as an ADF file or XML file. You can export your desktop account into either of these file formats using this application.
And then, you can copy that account into your laptop, by copying the exported file to your laptop and then using the program, import that file into your laptop. I hope this clears your issues. And read the thread about that program. You will get to know that its more useful than just managing accounts.
