/*
    MoveFiles.java
    Move files from the installation directory to another directory
      -- currently configured to move all DLL files from the installation dir 
         to the Windows\System or WinNT\System dir

    Notes: 
     1. Currently, this class file moves all DLL files from the installation/application
        directory to the Windows's System subdirectory if the installer is being
        operated on a Windows OS.
     2. You must include the *.DLL files in the Files panel; the files must be
        in the root of the installation directory, not in a subdirectory
     3. You must include this class file "After uninstaller created" in the Customs panel
     4. If you want to adapt this class to move other files to a different 
        destination, then change the destinationDir and the files that you want moved
     5. You are welcome to adapt this to meet your needs as long as you 
        only use it with the JExpress product
