Subject: bug#19360: Support for .adz=.adf.gz
Date: Fri, 12 Dec 2014 23:16:05 +0100

[Message part 1 (text/plain, inline)]

I hereby propose a trivial patch to add support for recognizing .adz files.
.adz files are just a shorthand for .adf.gz , in the same way that .tgz is
a shorthand for .tar.gz .

The patch is very simple: One part to recognize that .adz is a gzipped file
format, and one part to rename the output file to .adf . I haven't added
auto-renaming to .adz when gzipping, because people not familiar with the
de facto standard might get confused, though adding support would be
trivial.

Documentation that .adz is a de facto standard for amiga floppy disk images:

* http://fileformats.archiveteam.org/wiki/ADF_(Amiga)
* http://pcsupport.about.com/od/fileextensions/f/adzfile.htm
* http://www.fileinfo.com/extension/adz
I have also been playing with my amiga emulator and games I found on the
Internet, and there were a significant number of .adz files.

As far as my google skills suffice, I can't find any other meaning than
"gzipped adf" for .adz, so there should be no unintended consequences:
