x32 Card Records Multiple WAV Files

So to my knowledge FAT32 only supports file sizes up to 4 GB, and since drives must be in this format, is it normal for an hour long recording session to split into 8 or so different WAV files? If so, this doesn’t make much sense because it takes a ton of time to splice together 8 takes of 32 tracks.. I can’t find anything in the documentation that talks about this but we’ve been recording services that last around an hour or so and the recordings always split up if over a certain amount of time.
