You can also, instead of -bytes=2GB, use -number=4 if you wish to split the file into four equally-sized chunks the size of each chunk in that case would be 1 610 612 736 bytes or about 1.6 GiB. (Just substitute your own.) Then, I split them into segments approximately 2 GiB in size each the last segment is smaller, but that does not present a problem in any situation I can come up with. Here, I use truncate to create a sparse file 6 GiB in size. My6gbfile my6gbfile.part00 my6gbfile.part01 $ split -bytes=2GB -numeric-suffixes my6gbfile my6gbfile.part For example, on Linux you can do something similar to: $ truncate -s 6G my6gbfile However, if you split the file into multiple files and recombine them later, that will allow you to transfer all of the data, just not as a single file (so you'll likely need to recombine the file before it is useful). So you cannot copy a file that is larger than 4 GiB to any plain FAT volume.ĮxFAT solves this by using a 64-bit field to store the file size but that doesn't really help you as it requires a reformat of the partition. The 4 GiB barrier is a hard limit of FAT: the file system uses a 32-bit field to store the file size in bytes, and 2^32 bytes = 4 GiB (actually, the real limit is 4 GiB minus one byte, or 4 294 967 295 bytes, because you can have files of zero length).

Natively, you cannot store files larger than 4 GiB on a FAT file system.
