It would be reeeealy usefull to be able to burn DVD's from:
ISO-image inside multi-file-rar archive.

/F

[lfcrule1972]

Why ? ImgBurn is not an archive program so I would never expect it to be able to decompress any files I wished to burn.

[cornholio7]

why would you want to rar them in the first place?

[lfcrule1972]

Mmm I am guessing he wants to unrar them corny but you might be right in which case that makes me even more

[mmalves]

It would be very useful, indeed, and isn't hard at all to implement, but we all know where most multi-file RAR archives come from, don't we?
Of course, one could argue that compressing an ISO with RAR could drastically decrease the size (mostly it does), but I don't think it would stick.

[lfcrule1972]

Yeah but if it was a film why wouldn't you un-rar it first ? This just seems a bit lazy to me.......

[dontasciime]

Rarring up an ISO with video material within the ISO rarely decreases the size by more than a couple of meg.

[mmalves]

Split RAR archives are used more for splitting the data for easier transfer over the (unreliable) Internet than for the compression.
By the way, ISOs of applications/games do compress quite well, even past the point of having a dual-layer ISO fit in a single-layer disc.

[dontasciime]

Not many, if any applications are on dual layer.

Games fair enough.

for mpeg4 stuff and any form of already compressed material like mp3s not much gain in time taken to compress versus a small saving of mb

Split archives for file sharing uploading services, yeah, but for download , get right and the many resuming download managers.

The ability to resume doesn't mean that you're getting the file without errors. In fact, most download managers, by default, don't rolback when resuming.
This is so true that almost everywhere you find CRC/MD5 sums to check if the downloaded file wasn't modified, regardless of size. Even ImgBurn has it on its download page.

[dontasciime]

The one I use and have always used is Getright and it rolls back when resuming by default.

I cannot remember the last time i downloaded a file that had errors.

And what has this got to do with being able to burn ISO from within rar

LOL You will be quoting my spelling mistakes or my punctuation next

[mmalves]

Sorry, I didn't mean to be pedantic. I try and quote the relevant part so one doesn't need to read the whole topic to understand what I'm talking about.

I was just trying to point out that there are valid reasons to store ISOs inside RAR archives, and if ImgBurn supported burning that, it'd be awesome.
But I doubt very much that LUK will ever implement that, since he wants to have only one EXE with absolute control over it, and to support RAR he'd have to use UnRAR.DLL and/or other external DLLs.

Well yes. But still it would save some time for people that are lazy. Several minutes each time un-raring is not needed.

And for what I have unserstod it would not be to harde to implement. Just concatenating the data inside the rar-arachive that mostly not is compressed, just follwing the headers inside the arvhive to find all data-files and remove the headers from the files.

Anyhow, requested by me. Its up to you.

[lfcrule1972]

Yeah it's your request I just can't see the point, for e.g. a rar'd DVD Video ISO will not play on any players that I know so it seems pretty pointless - don't worry I am obviously missing the point somewhere here.

Well... yes you are.
Of course I do not want to burn the ISO on the DVD. I want to create a DVD from the ISO that recedes inside a rar-archive.

So to what I want in details:

1. I backup my DVD to an ISO-file on disk just as normal.
2. I archive the recently created DVD-iso in a multi-file rar-archive.
3. Later I want to burn a DVD from the ISO that I previously made. (or some may say received in a some other way, what do I know? )
4. I want to do that using ImgBurn without first un-raring the image to disk, I just let ImgBurn find the ISO inside the rar-archive and burn a DVD using the ISO as source on the fly.

I just want to keep my rared ISO's and the player i XBMC (XBOX MediaCenter) can play the rar:ed ISO.

Still thinks this would be an awsome feature!

you still have to take the time to rar the ISO in first place, how many copies will you need to justify the time taken to rar it in first instance against having to extract it, eg 1 copy 1 extraction. not worth the hassle for little saving.

[lfcrule1972]

Thanks for clearing that up for me Frog, typically how much space do you save by rar'ing these .iso's ? Before and after size I mean ?

Thanks

I agree with donta. Why would you bother? Yes, XBMC can extract then play an ISO contained within a rar file but what do you gain? HDs are so cheap these days it isn't funny. Farting around with archives to save a meg or two seems pretty pointless.

As I said before...

Some peopled obviously does not like the feature; however I think is would be fantastic! Like a wet dream coming true!

[Shamus_McFartfinger]

The only reason I can think of for wanting this feature is being able to extract and burn multi-rar torrent files. Some might argue that they seed linux distros but it's a pretty weak arguement when they can be downloaded directly from a webpage alot more quickly. I don't like your chances of having this implemented.
