Windows 7 burn files support the new format - flash can also "engraved"

As the price fell below the 200 yuan mark, DVD burners have become the standard configuration of mainstream computers, but in actual use, many users do not Full use of it is indeed 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 burning optical drives. With Windows 7 CD, we don't have to buy flash memory anymore. So, can burning discs under Windows 7 really be the same as flash? Let us try it if you don't believe it.

"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 “Burn Disc” prompt window will pop up. You can choose two types of burning. We choose “Similar to USB flash drive” to use the burning disc like flash. Then set the title of one disc, and the other type of recording is only suitable for burning multimedia files such as MP3, AVI, etc. (suitable for multimedia disc player, unable to edit or delete files after burning). Then click the "Next" button, the disc will be formatted, and then you can't burn it in other ways.

Formatting will consume part of the space (the 702MB burned disc takes up 5MB, which is obviously trivial), when the burned disc has become a flash memory, we can copy the file to the disc multiple times, at the same time It is also possible to delete files, and all operations are not different from flash. There is a process of closing the section when reading and writing the disc, so that other computers can recognize the disc.

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 Is the previous system working properly? First, we put the CD into the recorder of the computer on which Windows Vista is installed. The results confirmed that Windows Vista can add and delete files like Windows 7. 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.

"Flash" capacity is getting smaller and smaller

Many friends may think that Windows7 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 Windows7 formatting is still considerable, for example: single-layer DVD+R has 4.37GB, and double-layer DVD+R even has 8.4GB, so we will take these oversized burn discs. It is definitely enough to do 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.
