Save A BNDL for Mac

From Thomas Tempelmann:

Save A BNDL is a tool that allows you to update the Desktop Database selectively. Its most common uses are: - If you have multiple copies of the same application, each with a different version, then you can use Save A BNDL to select which one of the copies should be launched if you open (double click) a document created by those applications. - If some icons are not correct, or dragging of files onto an application does not work after you installed a newer or older version of an application or after you have rebuilt the desktop, you can fix this problem using Save A BNDL.
