The role of the Data folder
The Data folder is a folder for storing system and program data, such as software settings and installation packages. Each folder in the Data folder represents a different type of data storage folder. Regardless of whether the Data file refers to the file name Data or the extension data, it is a data file customized by the system or program. Data is a backup file for data storage, which can generally be opened with meidaplayer, notepad or word.
The Data folder mainly contains the following folders
1. Data/data/ contains the mobile phone system files and the data files for the software you install. If you delete it casually, it will cause the computer to crash or be unable to boot.
2. Data/dalvik-cache/ is the residual data of the uninstalled software. After deleting and restarting, you will find that the phone memory has increased. The data files in this folder can be deleted at will, but the first boot speed will be slow after deleting the data in this folder, but it will be normal after that.
3. The original meaning of data/app is the application program, which is the system application folder (often said to be the folder that needs to be changed when streamlining the system).
4. The original meaning of data/user refers to the user. This is the folder where user data is stored (such as your WIFI settings and lock screen password).

is an electronic computing machine used for high-speed calculations. It is known as "the most advanced scientific and technological invention of the 20th century." one". Computers are composed of hardware systems and software systems, and have many functions such as numerical calculations, logical calculations, and storage memory. Its application fields have expanded from the initial military scientific research application to various fields of society, driving technological progress on a global scale. The hardware system includes: chassis (power supply, hard disk, disk, memory, motherboard, CPU-central processing unit, CPU fan, optical drive, sound card, network card, graphics card), monitor, UPS (uninterruptible power supply system), keyboard, mouse, etc. (It can also be equipped with headphones, microphones, speakers, printers, cameras, etc.). Home computers generally have onboard sound cards and network cards on their motherboards. Some motherboards have integrated graphics.
