editSuggestions to add:
- MIME type application/octet-stream
(given that the default if none is given is often text, so that you get the dreaded text rendering of dmg file, forcing the control-click option).
- Note in the entry that because of the above problem, it's often wrapped insomething else, e.g. xxxx.dmg.bz2 or xxxx.dmg.zipSantaduck 07:39, 31 December 2005 (UTC)
I looked on the Drop2CD site in the external links section, doesn't appear to support DMG, any ideas? 11:51, 7 May 2006 (UTC)
What about technical details?
editI think that this article needs information about the technical details behind .dmg. There exists a couple tools for converting dmg's to ISO-9660 image files, but no real information about the format. It must be similar to .iso considering that it can be converted via Perl, but I'm sure it has some plist-related information included and whatnot. -Matt 16:49, 28 June 2006 (UTC)
- There exists no formal documentation on the format, as far as I know. I wrote the DMGExtractor tool from code originally written by vu1tur, and developed it a little further. I can say there's a lot of "garbage" data in the DMG files that I have no idea of what it is. However, some structure has been found, and I could write some about that, if anybody wants to know. --85.224.6.48 16:22, 2 November 2006 (UTC)
DMGExtractor malware?
editWho reported DMGExtractor as malware? It certainly is not, and I should know as I wrote it.. (: It's also open source, GPL'd. You can check everything.
Can you explain that claim? If something is wrong with the program, you should email me. My address is on the page for DMGExtractor. --85.224.6.48 16:25, 2 November 2006 (UTC)
Compression
editWhat sort of compression algorithm does Disk Utility use if you select to create a compreessd DMG and how does it compare with other methods of compression? —The preceding unsigned comment was added by 71.105.64.207 (talk) 08:52, 19 December 2006 (UTC).
Gzip iirc. T3h 10:16, 14 February 2007 (UTC)
It is possible to use BZIP2 compression in a disk image from OS X 10.4 onward. Though I think you need to go to the command line utility hdiutil to do that. --Unsound 12:33, 9 April 2007 (UTC)
