Understanding the difference between the Live File System and Mastered disc formats

If you have burned CDs using Windows XP, you are already familiar with the Mastered format. The latest version of Windows offers a new format, called Live File System. Discs that use the Live File System format are often more convenient because you can copy selected files immediately and as often as you want, as if the disc were a floppy disc or USB flash drive. On the other hand, Live File System discs can’t be used in all computers and devices. Use this guide to understand the difference between Live File System and Mastered discs:

Discs formatted with the Live File System option:

Work like a USB flash drive or floppy disk, meaning you can copy files to disc immediately without having to burn them.
Are convenient if you want to keep a disc in the burn drive and copy files whenever the need arises.
Are only compatible with Windows XP and later versions of Windows.

Discs formatted with the Mastered option:

Don’t copy files immediately, meaning you need to select the entire collection of files that you want to copy to the disc, and then burn them all at once.
Are convenient if you want to burn a large collection of files, such as a music CD.
Are compatiable with older computers and devices such as CD players and DVD players.

Why are there different versions of the Live File System format?

Each version of the Live File System format is compatible with different operating systems. Depending on which computers you plan to use a disc in, you might need to select a different version of Live File System. If you plan to use your disc on the latest version of Windows, however, you will never need to change the version of Live File System you use. If you need to make discs that are compatible with earlier versions of Windows, use the table below to select the right Live File System version for your needs:
