Although you can copy data up to 2 TB on an external drive using FAT32 file system. This problem occurs when you try to copy or move a file larger than 4 GB to an external hard disk or USB flash drive which was formatted using FAT (also known as FAT16) or FAT32 file system.įAT and FAT32 file systema have some limitations and you can’t store a file on FAT and FAT32 file systems which is larger than 2 GB and 4 GB in size respectively.
My USB drive capacity was 32 GB and there was sufficient free space on the USB drive, still Windows was unable to copy the file and displayed file too large error message. Windows was unable to copy Install.wim file to my USB drive.
Recently while copying Windows 10 setup files to one of my USB drives, I got this error message as shown in following screenshot: You get only “Cancel” button to terminate copying/moving operation. The file is too large for the destination file system.
