: Standard PS2 formatting struggled with modern high-capacity drives, often capping usable space at 2TB. The exFAT Advantage
FAT32 on OPL was notoriously picky about file fragmentation. If you copied a 3.9GB split file and your USB drive was dirty, OPL would freeze on a yellow or orange screen. exFAT handles fragmentation more gracefully, and OPL’s exFAT driver is optimized to read fragmented files without crashing.
– While exFAT supports large files, a heavily fragmented ISO can still cause stuttering. Use contig (Windows) or defrag occasionally.
