Flipper Zero support **optional** micro SD-card for expanding file system. It can store additional assets, plugins, libraries and so on. There is official SD-card image supplied with firmware updates, user can upload it using desktop firmware update util # Supported cards - micro SD HC class 1? **TODO: What actually types are NOT supported?** - FAT/exFAT filesystem - GPT and MBR partitioning table **TODO: Not clear in FatFS library docs** - Max size: up to 2TB **TODO: not tested, on 8GB confirmed** - Read/Write speed: up to 500 kbit/s **TODO: not clearly tested** - Built-in filesystem **TODO: not sure** # File manager File manager allows user to: - See information of filesystem - Format sd-card to exFAT - View files list - View file info - Run executable file: `.bin`, `.py` - Delete file ## SD-card not inserted If SD-card is not inserted, statusbar is empty. File manager application menu only shows help text "SD-card not found". **TODO:** Do we need `Scan for sd-card` action when card not found automatically?  ## SD-card inserted and mounted correctly When SD-card with correct fylesystem inserted, Flipper automatically trying to mount filesystem. If filesystem mounted correcly, the normal SD-card icon brings in statusbar.   ## SD-card inserted and mount failed If SD-card cannot be mounted because of not supported filesystem or any other reason, statusbar icon indicates this error. User can go to `File Manager` and see the info about failed card and the exact error code or full message. Also can format the whole card to supported filesystem and partition table.   ### Card Info Press `← Left` to see the card info: - Size - Partition type: GPT, MBR - Partitions with title and size  ### Format (erase card) Press `→ Right` to format card. One action should completely erase card and create one parition with recommended filesystem (exFAT?).
