Copying Files Over 4GB to a USB Drive Fails With 'Not Enough Space

copying files larger than 4GB to my USB drive fails with a "Not Enough Space" error, even though the drive has 128GB of free space available on Windows 11. Despite having plenty of storage, the transfer is blocked, and the error persists, making it difficult to move large files to my USB device without splitting them into smaller parts or using alternative methods.

    Hi Finebns, this is usually the USB drive format. If it is formatted as FAT32, individual files cannot be larger than 4GB even when the drive has plenty of free space. Back up the USB drive first, then format it as exFAT or NTFS. For a removable drive used across different devices, exFAT is usually the easiest choice.

    Hello bro, I think I have the same issue with you, maybe try to formatting the usb and change the type of the usb to EXFAT in the format window, maybe it'll work, because back then I have the same problem with you and it was the problem with the usb type, you need to format it to EXFAT, not NTFS, it should be working now
