SD Card Layout
The PX4 SD Card is used for storing configuration files, flight logs, mission information etc.
:::tip The SD card should be FAT32 formatted for use with PX4 (this is the default for SD cards). We recommend that you reformat cards that are using a different file system. :::
The directory structure/layout is shown below.
