!!! warning "Data Corruption" To avoid any data loss or corrupting the SD card, users should disable all activity with the SD card before removing it from the RA6M5 Thing Plus.

The [FATFileSystem library](https://github.com/arduino/ArduinoCore-renesas/tree/main/libraries/FATFilesystem) built into the Renesas-Arduino core, supports µSD cards with a **FAT32** file system *(i.e. SD cards **up to 32GB** in size)*.

- While users may be able to use cards with a higher storage capacity, we highly advise against it. As users may experience data loss due to a corrupt file system *(i.e. SD cards with a storage capacity greater than 32GB are not meant to be formatted with a FAT32 file system)*.

SD Card - Test

The Renesas-Arduino core includes a built-in FATFileSystem library that controls the SD host interface. The library that supports SD cards with a FAT32 file system (i.e. SD cards up to 32GB in size). Users can find an example sketch in the File > Examples > Storage > TestSDCARD drop-down menu.
