eSOL's PrFILE®2 exFAT File System Adopted in Nintendo Switch Lite


Tokyo, Japan. November 12, 2019 - eSOL, a leading developer of real-time embedded software solutions, today announced that its PrFILE®2 exFAT file system has been adopted for use in the Nintendo Switch Lite, a dedicated handheld play game console marketed by Nintendo Co., Ltd. that combines the console and controllers of the Nintendo SwitchTM in a single unit. Optimized for large storage media with capacities exceeding 32GB, PrFILE2 exFAT provides file access functions with high-speed reading and writing of data on memory cards that users may insert into the Nintendo Switch Lite. Those include high-capacity microSDXC cards as well as microSD and microSDHC cards.


The PrFILE2 exFAT file system supports FAT12, FAT16, FAT32 and exFAT. It can handle large files at high speed, including video, music, or photographs stored on high-capacity devices such as USB memory sticks or external hard disks that are too large for the legacy FAT32 file system. It also features numerous functions demanded by digital cameras and other consumer electronic devices, such as a rapid reverse-seek function for file pointers that is essential for features like high-speed rewind and functions for keeping damage to the file system to a minimum in the event of a disconnection of the power supply or memory device, while still retaining the features of FAT12, FAT16, FAT32, and file systems supporting VFAT (long filenames). It also provides support for the requirements of products designed for international markets, including multilingual support, dynamic switching of text codes and a Unicode support option.
