Share a microSD card with a computer as a USB drive, and take it back from your sketch.
The card has one owner at a time: the computer sees a removable drive, and the sketch can take the card back to write files (data logger, recorder, camera) and lend it again. The computer is told the media changed, so it shows the new files without unplugging. SDIO and SPI cards, FAT32 and exFAT, read-ahead and write buffering for full USB speed. For the Raspberry Pi RP2040/RP2350 Arduino core (arduino-pico).
