How can I copy a file to the users desktop?
There is no way within the AutoRun Wizard to copy a file to the users desktop. But you you could create a batch file to accomplish what you want.
Simply open notepad and type in
copy .\[your file name] %USERPROFILE%\Desktop
Save the file as [filename].bat (make sure there is not a .txt extension and its .bat)
Then copy the newly created batch file to your Base Folder. Once in your Base Folder you can auto launch the batch file as part of your autorun. When the user inserts the cd, the file(s) will be copied to their desktop.
