Well if your save data is corrupted, you cannot really fix that without a backup prior to it being corrupted.So I'm trying to use the Diablo 3 save editor and everytime I mod and reupload it it's telling me my save data is currupted how do I fix this can anyone help
exFAT has no file system-level encryption or compression support, and, like FAT32 before it, there is no journaling built into the exFAT file system. This means it has a much higher probability of data loss than with NTFS or HFS+

Save files are stored exclusively on internal storage so unless they're using emunand it's probably not that.yeah, avoid exfat if you do reformat, I formatted mine to fat32.
