How to distinguish useful files from your Android phone

There are a lot of files on your Android phone!! Files on the memory card can generally be ignored. But don't delete it indiscriminately.

For example, the suffix is called prop rc and so on are all system files, don't delete them randomly!! Especially after you root!! Otherwise, the consequences will be serious!

There is no specific conclusion on this.

Useful or useless is relative.

For example, some people don't need certain features, so the deletion of these files will not affect them, that is, they will be useless.

In addition, there are at least thousands of files in Android.,How can I explain it to you one by one.。

In addition to the name of the software you installed (including English), as well as the song you put in or **software package that looks like diom (installed**), it's best not to delete it.。

It can be judged according to the meaning of the English language. As listed below:

1. Android (system data).

2. Alibaba

3. data

Purpose: Store data information folder. You must pay attention to the data cleaning in this, otherwise the deleted data cannot be recovered.

4. backup (backup directory).

Purpose: A folder where you can store your contacts, text messages, or other data files at that time. If your phone is damaged or lost, you can import it here, but if you don't need it, you can delete it.

5. Cache

What it does: Temporary cache folder. After some software is opened, it will automatically cache files, so this folder must be cleaned up in time, otherwise it will cache a lot of garbage after a long time.

6. DCIM (photo album).

Function:Store**Folder,Generally, the mobile phone camera will be saved in this folder,If you need these**,Then you can delete it。

7. documents

8. system (system file).

Purpose: Store the default software folder of the system. Don't change the files in this easily, it may cause your phone system to crash.

10. Alipay (Alipay).

Purpose: A folder where Alipay's temporary files are stored. This folder is of little use and can be deleted.

First of all, if you don't know the purpose and folder name, try not to move, it is easy to have problems;

If you install the software, if necessary, the software will automatically create the corresponding folder on the SD card, for example, if you install the mobile phone QQ, the TECENT folder will appear on the SD, in view of the folders you see are in English, so, please understand the English or pinyin abbreviation of the relevant files before operation.

For folders you don't know, don't mess around, I once caused the system to be abnormal because of deletion.

Tap the phone app to clear.

Click on the Filter Manager.

3.Locate File Cleanup.

4.Click Save Analysis.

5.Finally, click on the file details.

There are relatively simple and convenient ways to do this.

Some mobile file explorers or third-party file explorers will automatically recognize and display the file with the corresponding software name.

Judge for yourself based on the folder name, for example"baidunetdisk"When the folder is translated, it is obvious that it corresponds to the cloud.

The name is not easy to judge, open the folder, go in and find, and some software can also be identified from the content.

By analogy, if the text files in the folder are not garbled, they may also be inferred from some of the words.

The audio in the folder is also a clue.

None of the above is easy to make, but it can only be said that according to the current standards, this software is a bit deep. Don't be afraid to go through the hassle and make sure that there are no important files in it, you can delete the folder directly, try which software is malfunctioning, and you can launch it.

Other ways may require the use of other software or even more advanced means.

The next software SD card cleanup,There are a lot of software that are English names,Some can be seen,For example, the wandoujia of the pea pod,If you are to manage the things in the SD card、

Hope this solves your problem!
