To enter File Management first, just enter four codes in the Search box:
(1) "Cache", that is, cached files, means that the mobile phone can automatically identify cached files. At this point, you can delete them all. By doing so, you will find that you have at least 10G of space.
② "backup", that is, backing up files, can be deleted by the same operation.
(3) "temp" is a temporary file generated by the system, and it can be deleted in the same operation.
4 "download". Operation is the same as above.
After this operation, about 50G of space can be vacated.
The main purpose of mobile phone memory:
1. Save pictures, animations, ringtones, applications and SMS MMS. The memory of a mobile phone should first assume the storage function similar to a computer hard disk.
I still remember the capacity sign from 1M to 2M on our SIM card, which is actually memory. In the past, some models did not support modifying pre-stored data at all, and phone books and short messages were saved on the card. The larger the capacity, the more information can be saved.
2. Basic operation. Call, send text messages, etc. , generally does not occupy a lot of memory.
3. Advanced operation. Unlock pictures, animations, multimedia messages, taking photos, surfing the Internet, etc. Some computers also include running themes, which occupy a certain amount of memory according to different situations. Especially when JAVA games are running, JAVA compressed packages are automatically unpacked, occupying memory. The game is not big and the memory requirement is not high, but the bigger the game, the higher the memory requirement.
In order to grasp the market, different brands and models of mobile phones and different body memories, major operators are developing gigabit or higher memory embedding to win the favor of more consumers and support it through external expansion cards, which makes the smart technology in the mobile phone market push to a new beginning.
