• 📁 File system: FAT32 (guaranteed to work), exFAT (requires manual adjustment), NTFS (partial support, possible errors). ext4 and HFS+ unrecognized.
• 💾 Capacity: up to 2 TB (tested on the Mi Box S), but for FAT32 Maximum file size: 4 GB.
• ⚡ Power: flash drives with high power consumption (for example, with LED-indicator) may not be determined - the prefix gives insufficient current.

If your drive is formatted in NTFS or exFAT, the Mi Box can see it but not open it, which requires either reformatting (with loss of data) or installing a third-party file manager like FX File Explorer or Solid Explorer that supports these formats.
