[SD card storage-related]
Why does the "Others" portion take up so much space?

The "Others" portion refers to the files on SD card which are files other than music, videos and pictures. For example, game data files from
installation package, or document formats which cannot be recognised by the phone system, files which phone backup file management can not
directly. Mostly due to the existing classification of media files, the phone will have a large number of non-media-files simultaneously, so the
volume occupied by “Others” will be relatively large, this is a normal phenomenon.
As the "Other" includes a lot of files which have different functions, there is no direct delete button. You need to identify and carefully
remove your own files. You can use the file manager file cleanup function to clear junk files.
