I want to back up a folder that has a size of more than 6GB and then put it into the CD-ROM. To do this, I compress the folder
zip -r /mnt/ESA/Oka/Old.zip Old/
and then split into smaller size using zipsplit. To check how many files will be created if we want to split into 600MB, type
and to split the file, type
zipsplit -tn 629145600 /mnt/ESA/Oka/Old.zip
and to split the file, type
zipsplit -n 629145600 /mnt/ESA/Oka/Old.zip
UPDATED
Uh it seems that there is a file size limit with zip. It stops at around 13MB.

so use tar and split instead. Type
to create the archive file, and then
to split the files and put into mysplitfiles directory. The files will be Old.tar.gz.aa, Old.tar.gz.ab and so on.
tar czvf /mnt/ESA/Oka/Old.tar.gz Old/
to create the archive file, and then
split –-bytes=600m /mnt/ESA/Oka/Old.tar.gz /mnt/ESA/Oka/mysplitfiles/Old.tar.gz.
to split the files and put into mysplitfiles directory. The files will be Old.tar.gz.aa, Old.tar.gz.ab and so on.
To recover them type
cat Old.tar.gz.* > Old.tar.gz
