A standard file system that has a flash drive coming from a store may not be readable by a media player or require manual permission confirmation every time you connect. TV, where data readability is critical for reproduction 4K-video.
The process of making the drive work is called formatting. Formatting is a file system markup procedure that creates a new structure for storing data. If you just delete the files, the structure will remain the same, and the errors can persist. So to work correctly with the Xiaomi Mi Box S or Mi TV Stick consoles, you need to do exactly the full formatting by choosing the right file system type.
There are several ways to do this: directly through the TV or console interface, or using a computer. The method depends on what you need the drive for.

If the flash drive will be used on both PC and TV, you better use the computer for more flexible settings.
Choosing a file system for Xiaomi TV and smartphones
The first step is to understand which file system your device supports. Android, which all Xiaomi gadgets run on, has limitations and preferences. The most common formats are FAT32, NTFS and exFAT. Each has its own characteristics that affect the compatibility and maximum size of a single file.

For modern devices like the Xiaomi Mi Box 4K, NTFS or exFAT are often the best choice. These formats allow you to write files of any size and provide faster read speeds. However, it is worth considering that some older TVs may not have built-in codecs for working with NTFS, requiring the installation of a third-party player.
