Unrar a file with DVD size.. (4.4 GB)

T-u-N-i-X · 2006-12-16 00:22:07

I have a directory that contains splited RAR files with a total size of 4.4 GB.. The files are on a FAT32 partition and I want to unrar it to an EXT3 filesystem partition..

I type the command:

unrar x connect.001.rar /home/tunix

and it starts to extract the ISO file.. But when the ISO's size is 2.0 GB, it gives an error:

"File length limit exceeded.." or something like that..

Anybody have an idea ?

Hiya,
the 2,0Gb is the file-limit on FAT32 partitions..

Try to copy the rar's to your ext3, and then unrar them

Actually, iirc, FAT32 has a file size limit of around 4GB, and partition size limit of 2TB.

I think this is further made a confusing issue in that Windows XP and 2000 won't allow the creation of a FAT32 partition larger than 32GB (maybe this has changed at one pointfor all I know), but it will utilize FAT32 partitions up to 2TB.

My guess is that even if you could work with files larger than 4GB, and can have parititions up to 2TB, when it comes to FAT32, there are probably reasons dealing with efficiency and performance, that you probably should avoid doing so.

I could be wrong about a few things here, but that is my understanding. I haven't used Windows in ages, so what I'm saying, may no longer apply for all I know. I just wanted to pass that on.

The bottom-line in relation to this thread, is that you would probably be best off to follow T-u-N-i-X's suggestion, any way you look at it.

Same problem, no solution so far:

I expect this to work:
$ cd /home/tunix
$ unrar e /mnt/fat/connect.001.rar

if you still have a windows partition, you could always run convert (its a command line thing) and convert it to ntfs, its a relatively safe process, i have done it on a few fat32 drives... then you won't have the issue with the filesize

timtux · 2006-12-16 13:25:11

Well, atleast me aint using fat. Just ext3

T-u-N-i-X · 2006-12-16 17:35:33

I think the problem is another issue... I've moved the rar files to my home directory which is an ext3 filesystem. I don't have any quotas and I have enough space on the hard disk 4.5 GB.. The resulting ISO file must be 4.4 GB.. It does the same thing when the ISO file reaches to 2.0 GB of size..

Does anybody know if UNRAR is limited with 2.0 GB in its free version ?

iarwain ben-adar · 2006-12-16 17:46:24

Stupid question,
but are you sure the rar isn't damaged?

Iarwain

T-u-N-i-X · 2006-12-16 17:49:14

I think, if any file would be damaged, it would output an error about it.. But I'll check it..

I'm trying the licenced rar in AUR now.. Hope it works..

timtux · 2006-12-16 17:57:37

Can you unrar it as root?

I *think* I saw something like that somewhere in these forums. You could try using rar from unsupported. Maybe it doesn't have this limit.

T-u-N-i-X · 2006-12-16 19:14:42

I tried the rar package in AUR.. It doesn't work either despite i've compiled it.. I don't understand why this happens.. I search Google, I looked RAR's page, it doesn't say anything about limitations.. There seems to be no problem about the rar files.. I don't like NTFS partition since it's still a pain in the ass to write it on Linux..

I really need a solution for this one.. Any other suggestions please ?

Snowman · 2006-12-16 20:12:05

Try doing a forum search. You might find the thread where I think that size limit was mentionned. Maybe there's a solution/hints in it.

T-u-N-i-X · 2006-12-16 20:59:28

I've tried to create a file with dd (3.0 GB) and it was successfull.. I also tried to extract it with the root account but the problem remains the same.. I really started to think that it's a problem of RAR generally.

unrar does not have any limits.

T-u-N-i-X · 2006-12-16 21:36:11

Where do you think the problem is then ? Can we do some diagnostic stuff ? Can you please suggest me something ?

I really don't know...
Have you tried to move rar files to ext3 before extracting?

lilsirecho · 2006-12-19 19:44:52

Suggest that you try a file-splitter to check out the limits....

mr.MikyMaus · 2006-12-19 21:57:03

I have no idea what might cause such behaviour, nor I can fix it.

But I came up with a workaround, splitting the file while it is being extracted. This can at least show if it is unrar's or filesystem's error/feature:) It may even solve your problem..

$ unrar p -ierr archive.rar | split -b2000m

If there is more than one file in the archive, you will have to extract them separately (unrar --help).

Take a look at

$ man split

before you proceed...

The above code will (is supposed to) generate few files 2000Megs per each, named xaa, xab, xac, ... which are nothing more than just splits of the full file.. you can then

$ cat xaa xab xac > extracted_file

to concate those files together.

The problem is you need at least twice more free space.

This method doesn't work either.. unrar always output the error of file size limit..

Hey, but I have unpacked 4G .iso to ext3 from 2G .rar file that was on FAT32 partition! (I've just remembered that).

Snarkout · 2006-12-22 16:33:27

If I understand correctly, you have a little over 4 gigs available on your drive, and you are trying to unrar a file 4 gigs in size. Are you certain rar doesn't unpack to /tmp or a scratch area before assembing the finished file? I'd really be very surprised if it's able to just unspin a zipped file on the fly, especially one that large.

Sorry, but I couldn't understand what you really mean with the last 1-2 sentence..

Snarkout · 2006-12-24 17:15:14

You are trying to unrar a file that's total size is over 4 gigs, correct? I believe that unrar probably needs to write some of the info for this file somewhere while it's unraring it. I imagine that it's writing this to /tmp or perhaps a "scratchfile" that is deleted after the file is completely unrared and reconstructed. This would mean that you have to have more space available than the finished unrared image takes up. It sounds to me like you are trying to unrar a large file into just enough space for the finished file. You may not have enough room on your disk or partition. This is just a guess, though, and I haven't researched unrar at all. Could you try to unpack that file on another disk or partition?
