    Hi I've recently discovered an issue which wasn't a problem until recently.
    I can't seem to transfer files larger than 2gb (but under 4gb) to any USB. I have tried multiple formats (fat32, mac OS extended), different files, and different USBs, and I receive a message stating...

    "The item “*file name*” can’t be copied because it is too large for the volume’s format."

    If the file was over 4gb I can understand due to the fat32 limitations, but 2gb?? I have never heard of that issue before!

    I am running High Sierra 10.13.1 on a 2014 macbook pro.

    IIRC, that’s an issue with Finder. Folks have said using Terminal (and the cp command) or a alternative to Finder (like PathFinder) work.

    This is what I use to get around this. The free version works fine for what you’re trying to do.

    It sounds like you need to reformat the USB drive. I know you said you tried multiple formats, but it has to be that. Make sure the partition scheme is GUID and the format is HFS Extended, Journaled. It should work. The problem with FAT is probably file size.

    I'm currently having the same problem with an Seagate 4Tb drive. OS 10.13.3 Macbook Pro. The strange part is that I do have files on the drive that are larger than 2 gb, but as of a few months ago, it's not letting me copy files.

    It's a defect in the Finder in 10.13. Use the terminal and cp command and you'll be fine.
