Problems making files bigger than 4Gb.

Riddick · 08-18-2004, 03:57 PM

I have SuSE 9.1 (which needs its own forum),
and have started video editing. I would like to dump the whole video to a file,
but it always (regardless of the program I use) stops at 4Gb (4096mb).

This happens with only Fat.

Please help!

A FAT16 system has a limit of 2GB per file = 2^16 - 1
A FAT32 system has a limit of 4GB per file = 2^32 - 2

So, you will need to use a 64-bit FS in order to pass the 4GB limit. You can dump the raw data to some other FS (ext2/3, reiserfs, xfs, jfs, ...), then split it up and move it to the FAT partition.

why are you using FAT !!!!

use ajournalling filesystem....
NTFS (for windows), or EXT3 / ReiserFS / XFS / JFS / for linux.

the file size limit on journalling file systems is in the thousands of terrabytes,,, plenty

Thanks very much! I'll now see how NTFS support is on Linux...
Because I'm dumping the files and I think my dad wants to work on them through windows...

hi

for NTFS u need to compile ur kernel for NTFS read write support

also see out for other options in ur kernel where u need to have the

HUGE FILESYSTEM SUPPORT

enabled
what is its value by default i do not know in case ur system does not works for files greater than 4 Gb then try compile ur kernel too

[qiote]also see out for other options in ur kernel where u need to have the

HUGE FILESYSTEM SUPPORT
[/quote]

only if you have a few terrabyes on your hard disk...

anyways.. Linux write support to NTFS is crap....
and windows suppotr for linux filesystems is ZERO.....

have a look on sourceforge.... some1 wrote a windows ext3 driver.. try using that, and format the disk as ext3.

"anyways.. Linux write support to NTFS is crap...."

he wants to do video editing in linux...
last time i read the kernel source documentation (when 2.6.7 came out) linux could not write to NTFS very well.

it can not change file sizes, delete files or make new files... only overwrite files of the exact size... which is almost useless.

the only way i can see both windows and linux writing to the same disk with files larger than 4GB is to use ext3, and attmept to install the ext3 windows driver.

but ofcource i could be wrong.

masand · 08-19-2004, 12:22 PM

hi
so do we have a option for that

what about the linux ntfs driver from sourceforge.net

does it works????i mean writing to NTFS drives

the ntfs driver comes with the newish kernels, i believe the sourceforge driver is the same as the one in the kernel.

like i said.. it will read ntfs, but write support is limited to over-writing files of the exact same size...

you cannot create new files. you cannot delete files, you cannot increace of decreace the files of files...

write support is almost useles.
