help
exFAT (Extended File Allocation Table) is a file system
designed for large-capacity storage devices.
Key features and recommendations:
- Target scenarios: Primarily used for storage media requiring
support for very large files (>4GB) or large partitions
(>32GB), such as high-capacity SD cards or USB drives.
- Resource cost: Enabling exFAT support will significantly
increase the code size (ROM footprint) of the file system.
- Recommendation:
For small-capacity storage devices (e.g., SPI Flash or
eMMC under 32GB), the standard FAT16 or FAT32 file
systems are perfectly adequate. It is strongly recommended
to keep this option disabled unless you absolutely need to
handle large-capacity storage, in order to conserve
valuable code space.
