File System Compatibility with the NI Linux Real-Time OS

The root file systems on NI Linux Real-Time OS controllers (such as but not limited to cRIO-906x, cRIO-903x, and myRIO) are mounted as a UBIFS virtual file system, but the NI Linux Real-Time OS is also capable of reading and writing to the following file system formats on external USB devices and network shared folders:

• FAT 16
• FAT 32
• ext2
• ext3
• ext4 (for Linux Real-Time PXI controllers only)
   

See Real-Time Controllers and Real-Time Operating Systems Compatibility to find out more information about the OS that get's used on your device. 

Although ext2 and ext3 are supported by the NI Linux Real-Time OS, they are not well-supported on the Windows operating system.  It is recommended that any devices needing to be used with Windows be formatted to the FAT32 file system.
