Copying a file a few mb smaller then 4gb to FAT32 fails with filesize error

software effected: teracopy 3.17.

filesystem Ntfs to fat32

filesize shown in this screenshot

hello, whenever i copy a file using teracopy from NTFS to fat 32 and the filesize is near 4GB limit of fat 32 teracopy throws a error message

these files copy just fine with explorer. they are just under the 4,294,967,295 byte limit of fat 32 (65,535 bytes less then the limit)

i have no idea why this happens with tera copy, but its annoying as iwanty to ensure checksums match easily between the backup and the restore
