splitting 6gig .sit file for DVD burning (free)

aaron128 · 05-19-2003, 06:22 PM

I'm looking for a freeware way of splitting a 6 gig .sit file for DVD-R backup. If the solution is command line, I would appreciate an example, as I am not too hot at CLI.

Ideally, the file will be recombined in OS 9, though that is not necessary.

thanks!

try this in terminal:

split -b 4000m file

I believe that this DOES work on large (>2GB ) files, if I remember correctly. The output is a set of 4G files with the names xaa, xab ..

do

man split

for more info.

That did the trick. I started out doing 4000m, but that was generating a bunch of 100mb files, so I poked around on Google and there seems to be a 2 gig limit. So I did 1.43 gig segments (4.3 / 3) ... that worked like a charm. Seems like I use 'cat' to get them back together?

thanks much!

If you wanted to fit this onto only 2 DVDs, you could split the file into 1 GB segments. Then put 4 segments together for a 4 GB file, and then put the other segments together for a 2 GB file (using cat).

Yep. The command cat part1 part2 part3 > complete would take "part1" and then add "part2" and then add "part3" and save the result as "complete".

I have often seen this technique for splitting disk images and such and wondered - is there any type of error checking going on. For example - when you cat the files back together - is it simply a brute force merging or will you get some indication if there is some sort of anomally that differs from the original.

I have a lot of different video format's and most the time it is hard to find a program that does all the different versions. So, in result I've started using the "cat" command..Can't believe I didn't use this sooner as it has worked everytime.
