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.

Android phones do have a lot of folders on their memory cards and SD cards, most of which are useful and can't be deleted. But it is true that some of them are junk folders, some are left over from installing software and uninstalling it, and some are empty folders of spare data that may never be needed in the map software, and so on.

As for whether or not to dispose of them, it doesn't matter. Empty folders don't take up much space, and deleting them at will may delete useful folders by mistake, so you can generally ignore them. If you really want to make your phone clean and refreshing, it is recommended to use software such as mobile phone guard and mobile phone optimization to clean up, and the possibility of accidental deletion is smaller.

Whether it is in the root directory of Android or on the SD card, all the files and folders in the system and data folders are useful, don't delete them casually, they are system folders; All other files or folders are files, and they won't affect anything after they are deleted, that's all.

Under the SD card directory of the mobile phone, the Android directory is useful, and the others are third-party applications or artificially generated. It is possible to install the ES browser to determine which directories belong to which third-party software.

This is usually the cache folder of the software you have installed. Others come with the system.

You can leave this alone! If it's useless, it won't spawn.

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、
