Burning additional files onto CR-RW

Thanks for quick response Deme. However, if I understand what you say, I don't want to simply re-use my disc (by erasing previous data or reformatting - is that what you meant?) but rather add files to a disc that already has content. I use PCs at work and keeping adding content to a disc time after time until it is full. I don't understand why it isn't as straightforward (if possible!) with my Mac.

Duane,
Many thanks for the prompt response. Thanks to you mentioning the term multi sessions I was able to track down reference on 'Help'. However, the multi session advice from Disk Utility 'Help' seemed incredibly long winded and, frankly, unHelpful - and why is it buried in the depths of that?

Let me explain where I'm coming from here;
I currently have a mac at home (converted after several years working in the media) but at work we have PCs. I hate 'em! They feel crude, slow and clumsy. I constantly wind the IT tekkies up with my bragging the prowess of Macs. However, all the CD burning I've done has been at work. The machines are a couple of years old and use an application called NERO. You open Nero, it asks if you want to add files to the CD, a window lets you browse your files, you choose what folders or files you wish to burn then you click on a 'Burn' button. It burns. Later, after perhaps burning other disks, you find you want to add more files to that original disc, you stick it in, click Nero and repeat the procedure - and so on 'til the disc is full.

Now Macs were bound to be simpler. So with my new Mac I confidently popped in my first CD. Great stuff! Drag your files onto the disc image and click Burn. The way it should be. But there it ends - and now I need to eat humble pie with my PC tekkies!

These are the opening lines from the 'Help' for multi sessioning;
"Normally, you can burn items to a recordable disc, such as a CD-R, CD-RW, or DVD-RW, only one time...."

That's outrageous! are Applemac users around the world wading through piles of CDs, using a new one everytime they want to record something?

I guess you've answered my query in as much as, no, I wasn't missing the obvious and if I've had to dig deep and appeal to find out if the facility exists or is easy to use, then something is definitely not right there.

Somethings gotta change.

Thanks for listening...
