As Fruit Bat /\0/\ points out, if you use CD-R disks in multisession mode, you can keep adding files to them until the disk is full.
I do it to store/backup applications, programs, utilities etc and it's a useful way of installing updates, new versions etc on other systems.
You start a disk in multisession mode (with Nero at least), give the Folder a name (make sure it makes it obvious what's on the disk) and keep dragging and dropping files onto the folder name before a burning session; make sure each new addition is Saved to the file.
Also keep a proper record of what's on as you can get a lot of items on one disk.
When the final item is to go on the disk, ensure that Finalise is selected to close the disk after the burn.
I've named most of my multisession CD-Rs as VariousOne, VariousTwo and so on.
Multi-session is very useful I keep adding photos to the same cd-r's just add them in a new folder with the event that they where taken at, sometimes months apart, eg added a folder saying first birthday, then added a folder months later named zoo trip at easter.
For short term portable storage I 'd recommend a usb pen they are far more economical, they've come down in price recently too. PC World always have some discount/promotion on one brand or another.
