format will consume part of the space (702MB burned CD takes up 5MB, obviously insignificant), then the burned disc has become a flash, we can copy the file to this multiple times The CD can also delete files, and all operations are not different from flash (Figure 2). There is a process of closing the section when reading and writing the disc, so that other computers can recognize the disc.
“Flash” can also be carved out
After inserting a blank CD-R disc, the available capacity of the disc is immediately displayed in the Windows 7 Explorer. Unlike other systems, the autoplay window will pop up. For security reasons, Windows 7 needs to manually open the burn disc to perform related operations. After opening the burning disc, the prompt window of “burning disc” will pop up, you can choose two types of burning. We choose “like USB flash drive” to use the burning disc like flash memory (see Figure 1). . Then set the title of a disc, and another type of burning is only suitable for burning bulk MP3, AVI and other multimedia files (suitable for multimedia disc players, can not edit or delete files after burning). Then click the “Next” button to start formatting the disc, and then you can't burn it in other ways.
“Flash” Capacity is getting smaller and smaller
A lot of friends may think that Windows 7 will regain space after deleting a file. In fact, ordinary burning discs (DVD-R, CD-R, etc.) are written once. Windows 7 simply hides deleted files permanently, and newly written files cannot occupy the space of deleted files. Therefore, even if you delete the files of the burned disc in Windows 7, the space of the disc will be less and less. Only use CDs such as CD-RWs and DVD-RWs that support multiple erasures to clone all the features of flash memory under Windows 7. However, the capacity of the currently burned DVD disc after formatting by Windows 7 is still considerable, for example, the single-layer DVD+R has 4.37GB, and the double-layer DVD+R even has 8.4GB, so we will burn these oversized discs. It is definitely enough to use flash memory. If you have a Blu-ray burner, the BD-R and 50GB BD-R DL discs with a capacity of up to 25GB are definitely comparable to the huge amount of flash memory.
How the system supports "Flash"
The file system that converts the burning disk into flash memory in Windows 7 is Live (UDF) 2.50, which belongs to the latest burning file system, then the CD can be used in Windows 7 previous systems. Normal use? First, we put the CD into the recorder of the computer on which Windows Vista is installed. The result is confirmed: Windows Vista can add and delete files like Windows 7 (Figure 3). In Windows XP, we can read the contents of the burned disc, but we cannot delete and edit the contents of the disc. This is because the file system of the burned disc of Windows 7 is higher than the file system supported by Windows XP (Live 2.01), and the file system of the burned disc supported by Windows Vista is the same as that of Windows 7.
As the price fell below the 200 yuan mark, DVD-burning optical drives have become the standard configuration of mainstream computers, but in actual use, many users do not fully use it, it is really a waste. Perhaps many computer novices are unpredictable for burning software such as Nero, and dare not try to burn discs easily. In fact, this problem can be solved by the burning function that comes with the easy-to-use Windows system. Now, we found that Windows 7 allows you to dig out the potential of a CD-ROM drive. With Windows 7 burning discs, we no longer have to buy flash memory. So, can you actually burn a disc with Windows 7 like flash? Let's try it if you don't believe it.
