    Is it at all possible to explore an incomplete DMG file?

    I occasionally get torrent reseed request for files I've deleted the original DMG file for. I am hoping it's possible to explore a newly downloaded incomplete version of the file that I can add the completed application to and therefore assist with reseeding.

    Hope someone here may know either way?

    Yes and no.

    You can review the file with a hex editor, but you will learn very little of value. The files of a disk image file may not be continuous. Certainly a partial torrent download will not be continuous and have many gaps in the file.

    What do you hope to gain by examining a partial download?

    Thank you for responding! It's only really for torrents that I have shared for over a month (many sites minimum share period) and then deleted the original file but kept the application. Then someone may request the file.. I just feel it good Karma to try to help them out.

    Probably not something I really need to concern myself with, but if I have the app anyway it could prove helpful especially with a dead torrent.

    When I do the same, with say a folder, Azureus allocates the files space from the outset due to the settings I have in place. I would just 1) re-download the torrent 2) open it in Azureus to create the folder and it's contents 3) stop the download 4) replace the incomplete file with the completed one I downloaded previously 5) restart Azureus. This obviously only works when the files match exactly.

    So my question relates to trying to find a similar method for the disk image. I'm hoping I could explore the DMG to replace an incomplete part with a complete part. My requirement is only for whole files and not ones split into RAR etc.

    Some sites get a little narked with re-post of the same file so this was my potential fix.

    It sounds like you have really good intentions, but even if you could do that, your idea is a big can of worms... Torrent relies on the file being sent being identical at all instances. The disk image you "re-create" in this manner would not be the same as the other versions floating around. If this is legal distribution of files, it would be better for you to just contact the people involved (or post) a new torrent seed with a disk image you create, so that people can latch onto your torrent and start distributing identical instances of the file you originated. If it's not legal, of course, you're on your own as far as I'm concerned. ;)

    Thanks for your input and honesty.

    I did think it was going to throw some technical issues into the mix. Sounds like what I wanted to do is actually NOT possible. That's fine.. I'm just the one to try for the impossible. :D

    Great advice both of you. Thanks!
