Hi all,

This question has been asked before (many times) but I did not find a clear answer here. The problem is that I'm trying to burn a file larger than 4GB using K3b which of course fails with an error (when adding a file). I have the latest K3b 1.0, growisofs 7.0, and yes - I choose the UDF filesystem. However, this still does not work for me...

The file is not too big - Nero on Windows has no problem burning it. The problem occurs only on Linux. Did any of you find a way to overcome this issue and could describe it here?

By the way - I know that I could split the file but I do not want to. I want to be able to open it (it is a wmv movie) directly from the disc without any special steps. Thanx

Not what you asked, but why not change it into a regular video DVD? It is relatively simple and will play on about anything that way.

Another workaround In this case I cannot change it to DVD because the file is HD-WMV and will not play in the same way... Besides, I really think that there should be a general solution to this and that we should not have to consider this problem case by case. Besides, the problem seems fairly simple - so there must be a simple solution !!!

I also wonder how this is going to work for Blu-Ray. Will we be able to burn laa...arge files on the discs or are we going to be forced to split them into chunks below 4GB?

I've installed Nero for Linux (demo) yesterday and was able to add a file bigger than 4GB to a project. Will try to burn it today and see if it works.

Maybe

From: http://en.wikipedia.org/wiki/ISO_9660

Normally, a file on a ISO formatted disc cannot be larger than 2^31-1 in size, as the file's size is stored in a signed 32 bit value, for which 2^31-1 is the maximum.

It is, however, possible to circumvent this limitation by using the multi-extent (fragmentation) feature of ISO 9660 Level 3. With this, files larger than 2GB can be split up into multiple extents (sequential series of sectors), each not exceeding the 2GB limit.

Empirical tests with a 4.2 GB fragmented file on a DVD media have shown that Microsoft Windows XP supports this, while Mac OS X (as of 10.4.8) does not handle this case properly. In the case of Mac OS X the reason is that its driver apparently does not support file fragmentation at all (i.e. it only supports ISO 9660 Level 2 but not Level 3).


In K3b: Highlight project->properties->Advanced->(All the way to bottom) ISO level->click level 3 dot


It is worth a try.

hello,

post your results with nerolinux please, I'm kinda tired of that bug now too.

Hmm... I do not have such option in K3b. Actually I do not have "Advanced" tab at all. Do I need to enable it somewhere first?

OK, I have finally checked Nero Linux. It burned the 4.2 GB file without any problems. It even suggested by itself that I have to use UDF and not ISO9660. What's even more important - the burned CD is perfectly readable under Linux - no problem with loading the big file...

My opinion? The standard Linux tools really need an update 'cause currently they are way behind commercial products (like Nero).

I could not figure out how to do screen shots here, so I put up a post on another forum. I think this will make what I was saying clear:

OK, I've found the option. In my K3b it is under "Custom" button in the "Filesystem" tab. Unfortunately changing to level 3 does not solve the problem. K3b still says that it cannot add files larger than 4GB

So still... the only solution is Nero...

In anyway, thanx for help lazlow.

another idea: you could use a dvd-rw (or +rw or ram), then format with udf (dvd+rw-format) and then just copy the file with konqueror or krusader like normal directory.
Unfortunately I don't have a large enough file atm to test that, but you could try while you're at it
