Discover New World Windows7 new feature CD can be used as a USB flash drive. I originally intended to save the "Struggle" after reading, I did not want to use Win7 less than a week. Surprise discovery!

In Windows 7, you can format the empty disc into "UDF system format", which is equivalent to U disk can be read and written multiple times, editing. Nowadays, the cheaper DVDs are more than one piece, which is equivalent to a 4G U disk that we can spend less than two dollars. Haha. . .

The following is my operation record:

★1 Insert an empty DVD disc, the system will not close the auto play function will pop up a prompt box (Figure 1), close it.

★2 Double-click the CD-ROM icon on the computer, the “How do you use this CD?” prompt box will pop up, there are two choices (Figure 2)

☆A: Similar to a USB flash drive (Save and edit files on each deleted disk at any time. The disk will work on a computer running Windows XP or higher) [Real-time file system]

☆B: With CD/DVD player (groups of burned files will not be edited or deleted after burning separate files, the disk will work on most computers) [Mastered]

In addition, the original data will be formatted and that part of the space is not available.
