splitting large files to smaller parts

i wanna split large files (larger than 1GB) to small parts.
i know i can use split/cat commands to do this, but is there any applications with a gui that can do the same? i have tried Karchiver, which can archive and then split files, but it is really unstable and slow...perhaps because of the large file sizes.

If it's an ascii file, you should be able to use console tools - I don't know what bash's largest integers are (long?), but something like:

for ((a=1;a<$lastlinenum;a+=$howmany));do [output lines] $a $a+$howmany > file_$a.txt;done

you need special brackets for $a+howmany to evaluate it, I don't know which kinds of brackets they are; I don't know what command you'd use for [output lines]

You can later just put them back together by

cat file_* >> wholefile.txt

Hope this works for you.

thanks for the suggestion, but my point was not to use console. if i were to use console i would think its easier to simply use split command and then cat to join them.
but i dont want to use console...i want to use an application with a gui.
but thanks anyways
