DiskDoubler is a data compression utility for compressing files on the Apple Macintosh platform. Unlike most such programs, which compress numerous files into a single archive for transmission, DiskDoubler was intended to compress single files "in place" to save space on the drive. When such a file was opened, DiskDoubler would decompress the file before handing it off to the application for use.
The DiskDoubler software seems to be old or discontinued.
Such programs may not work on modern operating systems properly, are no longer available and supported by their original developers, or are simply obsolete for their purpose. Sometimes companies offer limited support through their website.

However most, if not all directly associated file extensions should be listed with its appropriate program. Although its likely, that some file extensions may be missing from the list of associated file extensions with the application, yet they can be opened, be part of, or otherwise be associated with the program.
