CD Burning in Windows XP

How to Burn CDs Using Windows XP, you can copy tracks either to a compact disk–recorder (CD–R) or to a compact disk–rewritable (CD–RW).When you first insert a blank CD into your CD recorder drive, Windows XP opens a dialog box asking if you want to open a writable CD folder. Depending on what your needs are, you can choose to open a folder or not. The Always do the selected action check box remembers your choice if you don't want to be prompted every time.
With the folder open, you can drag and drop files and/or directories into it. Windows XP makes a copy of these files in a special staging area until it is time to burn the CD, and displays a list of the contents waiting to be recorded. At this point, you can still change your mind about any of the contents in the folder. Simply select and delete any files or directories you don't want copied.

They are removed from the staging area only, and your original files are not deleted.
If you attempt to place more content on the CD than its capacity allows, you will be notified. Typically, a standard CD holds 650 MB, a high capacity CD holds 850 MB. When you're ready to record, just click Write these files to CD in the task bar to the left. The CD Writing Wizard opens and prompts you for a label for the CD. You can enter up to 16 characters. Click Next and the wizard displays a progress bar indicating the status. If you did not select the Close the wizard after the files have been written check box, then a final dialog box opens, asking if you'd like to make an additional copy of the same files.

When you're actually doing this for the first time, by this point you're saying "Wow!," or "Cool!," or "Groovy!," or whatever vernacular your generation uses. But wait! There's more!
Let's say you forgot a file. Or better yet, let's say you put a mere 200 MB on the CD, and it's really bugging you that there's 500 MB going unused. Penny–pinchers never fear, it's not too late to add more!
Simply drag and drop more files into the folder and they will be added to the waiting list for the next recording session. Windows XP fully supports creating multi–session CDs. Just be aware of the fact that adding a file or folder of the same name replaces the prior version.
