|My response at #3 was a simplified overview in the hope that you could fix your issue quickly. Below is a little more which should help your understanding. You might just prefer to jump to the final XP link (Deleting) at the end of this response:|
There are two ways to write to a CD-RW.
One is "on the fly", which means you simply copy/paste the files onto the disk in the same way as you would with a USB flash drive. This requires that you first format the disk for use in this fashion. Formatting allocates writing areas and removes any files that happen to be present. You can then simply add and delete files from it in the same way as you do for any other files on the computer. This only applies if you have an "on the fly" writing feature available. If you use Erase (from My Computer) then formatting is also removed.
The other way is to use "disk-at-once" for your CD writing. This does not require the disk to be formatted first. If you used a third party program this gives you a screen upon which you enter the files you want added (either browse for them or drag and drop - depends on program). You use the same program to delete any unwanted files.
As you were unsure about format then it is about certain you used "disk-at-once" so I have therefore "struck out" my mention of format in #3 (last line). Erase should do the trick for you (which can also be used to "un-format" a CD-RW disk).
The above is very general. Here is the info for XP in particular (including the use of "send-to" which you might have used):
Hope all this helps rather than adding to the confusion.
Always pop back and let us know the outcome - thanks
