I have a 6 GB .ISO file (a PC game) that I would like to split into two 3 GB files so that it would fit into 2 DVDs.

How can I do this? Is there some application or command that can do the job? And after I split it, how do I merge it back together later?

What kind of disk would it be? Data, DVD-Video, Bootable? etc... –  BloodPhilia Jul 23 '10 at 8:36
    
of course it would be data, unless there's a bootable pc game –  soul Jul 24 '10 at 6:52

Either rar to split it into parts, or extract the individual files from the iso with something like imgburn and make a new iso at the destination.

if you're on linux you can do:

split -b 3G big.iso part

to split the big.iso into 3GiB parts named partaa, partab etc.

then use cat to put the files back together:

cat part* > big.iso

See man split for more information.

There are various File Splitters that work in DOS. Then use COPY /b file1+file2+file_n Originalfile to reassemble.

Or try http://www.filesplitter.org/

WinRar is quick and easy.

You can use a file splitter/joiner utility to achieve this. HJSplit and GSplit are two good options. Both are freeware and very easy to use. HJSplit is a 344 KB file that does not need to be installed. A portable edition of GSplit is also available with no required installation.
