There is an relatively easy fix for the problem of a file being too large for the USB drive: you need to change the file system of the removable drive from FAT32 to a more modern system, such as exFAT of NTFS.īefore you proceed, check the USB drive you are about to modify for any important files of yours, and if it has some, copy them out of the drive to some other location (such as the PC or a different removable drive). If you've encountered an error while copying a large file (4 GB or larger) to a USB drive that has plenty of free space, reporting that the file is too large, it's probably because the USB drive has been formatted with the FAT32 file system that has a limit on how large a file it can have.Įncrypt and password-protect external drives with USBCrypt encryption software for Windows 11,10,8.
