Support for the International Organization for Standardization (ISO) Image
The CD-RW recording feature that is built in to the Windows XP shell does not support the creation of an International Standards Organization (ISO) image. To create an ISO image in Windows XP, you need to install a third party utility that supports this feature.
An ISO image file is a snapshot of the data and layout of a CD, saved in ISO-9660 format. ISO image files are widely used for storing CD content. ISO is a common CD image format for DOS, Windows (Joliet ISO extension), Linux (RockRidge ISO extension), and other operating systems.
Description of the Staging Area
To facilitate CD recording, Windows XP uses a staging area to store the data for recording, which is located in the following hidden folder:
Drive_letter:\Documents and Settings\username\Local Settings\Application Data\Microsoft\CD Burning
In addition, the information in the staging area is copied to a monolithic disc image file before you record the data. By default, this file is named "Cd burning stash file.bin" and is located in the root folder. You can change the location of the file in the CD recorder Properties dialog box.
Note Because the Local Settings folder is a hidden folder, you will have to change your Explorer settings to be able to see it. To do this, follow these steps:
1. Start Windows Explorer.
2. Click Tools, click Folder Options, and then click the View tab.
3. Under Hidden files and folders, click to select Show hidden files and folders, and then click OK.
How to Move Files to the Staging Area
There are four methods that you can use to copy files to the staging area:
• Method 1: You can use a drag-and-drop operation to move the files to the CD burner icon.
• Method 2: Right-click the file (or files), click Send To, and then click Name or Drive Letter of your Writable CD.
• Method 3: Click the file, click Send To on the File menu, and then click Name or Drive Letter of your Writable CD.
• Method 4: Copy the files manually to the staging area.
How to Initiate the Burn Process
There are two methods to start the burn process after the files are in the staging area:
• Method 1: Under CD Writing Tasks, click Write these files to CD.
• Method 2: Right-click the CD drive, and then click Write these files to CD.
