The drive is most likely formatted as FAT32 system. This is a typical partitioning format that is supported by practically all computers (windows, linux and mac os). FAT32 limits file sizes to 4GB and device sizes to 8TB. For you to be able to store a file greater than 4GB in size, you'd need to reformat the drive to either ExFAT (file size is limited to 16EB, or 16 BILLION TB) or a MacOS partition format (called HFS plus, file size limited to 8EB, or 8 BILLION TB). I'd recommend the MacOS partition format for it's reliability, but only if you're working in a strictly Mac OS environment. HFS plus is NOT supported by Windows. If you need to transfer files between computers of various OSs, I'd recommend ExFAT.

Note: Changing partition formats WILL DELETE ALL DATA ON THE DRIVE, so make sure you back up all the data on the drive before you start.

  1. Back up all your files on the USB drive onto a secure location on your Mac.
  2. Open Disk Utility by searching it in spot light or opening it from /Applications/Utilities
  3. Select your desired drive on the left side.
  4. Go to the "Erase" tab.
  5. Choose your desired partition format from the drop down menu, and name your drive as you please.
  6. Click "erase"
  7. Restore the files back to the drive.

I think you will be better off using some cloud storage space for Mac to PC transfer.

This error doesn't appear for uploading to Google Drive, Dropbox or Microsoft Cloud things like that.

If your internet is robust, transferring using cloud is actually even quicker than hard drives

Nonsense, Internet data transfer rates are much lower than hard drive transfer rates.

Real simple... stop wasting time with your personal files . Online there are 1000's of channels to watch; 100's of movie providers like NETFLIX, HULU, AMAZON, CRACKLE, YOUTUBE. Etc. And between the "free 30 day trials" and regular free programs, it's easy.


I am sure you could watch TV 24/7 for ten years and still miss a lot.


Oh? You like to work with computers? Program? Be creative instead of keeping a couch warm? Then, why waste your short life with "canned" junk on TV?


You have a choice: be a watcher, or be a doer. Enjoy your live. Live your life, not just watch someone else's idea what life should be. ( Those are actors out there, not real people with real feelings and ideas. They do and say what they are paid for. )


I hope this helps. We know how difficult decisions are.

It's now 2016, using macOS 10.12.2, and I ran into the same situation, with a 32GB MS-DOS (Fat32) formatted USB flash drive. Except this happened:


After formatting the drive, I was able to copy onto it a 31GB .imovielibrary with no problem. I was using the drive as a backup as well as sneakernet to copy the library to a different Mac. After I finished the intended .MP4 movie, I erased the drive and attempted to copy the 8.74GB movie onto the drive. The nasty "This item can't be copied because..." error showed up. I bombed the Finder just to be sure it wasn't at fault. Nope. Still had the problem. What The?!


But as per advice here, I RE-formatted the USB to ExFat and was then able to copy the 31GB file. Great! Except why was I successful with a 31GB file earlier?! Figure that out. (0_o) I wasn't using any verboten characters. The file name wasn't too long. All I can say is: Microsoft. (;_;)
