SD Card Manager
Keep test data on the card and take it home for analysis
Manages TF card storage: mount, format, browse directories, preview and delete files. Run logs, recorded data and capture files all land on the card and can be copied to a computer at any time.
On-device formatting to FAT32 solves the common problem of large retail cards shipping with exFAT that cannot be mounted; writes are synced in batches to avoid the classic "file exists but is 0 bytes" pitfall.
