The APPLEDOUBLE file extension is associated with the AppleDouble file format introduced with the first Apple Unix operating system called A/UX.

AppleDouble is similar to AppleSingle file format. However AppleSingle contains resources and data in one single file and AppleDouble in two separate files.

AppleDouble resources part with Finder meta-data has .appledouble file extension and data part is stored in original file format with original file extension. AppleDouble format is better for transport data through Internet, because non-Mac users can open the original file without other decoding like AppleSingle format.
