Fixes for 'File Is Too Large for Destination File System' on USB/External Hard Drive
"Yesterday, when I tried to copy some large files including Windows 10 ISO files, the backup images of my operating system, movies, personal video files, and other data to my 32 GB external hard drive, I received the error message saying "The file is too large for the destination file system." I don't know why it happened as there was enough free space on the disk. Can anyone help?"
What's The Reason for The 'file is too large' Error?
When facing the "The file is too large for the destination file system" issue in Windows 10/8/7, you might get confused about why you would not be able to copy the file to your USB flash drive when there is sufficient free space.
The problem occurs because one of the files you want to transfer is larger than 4 GB and your USB flash drive is using the FAT32 file system, of which the maximum file size is 4GB. For a FAT16 USB flash drive, the maximum file size is 2GB. There is a built-in limitation in the FAT32 file system: Although the total size of the files you can store on a FAT32 drive could be up to 2TB, you cannot save an individual file that exceeds 4GB on it.
2 Efficient Solutions to Fix Your Problem
After figuring out the reason for "The file is too large for the destination file system" issue, you can fix it with ease, that is to convert the file system from FAT32/FAT16 to NTFS. Here we will introduce you to two easy solutions. We will show you how to use these two methods to fix the "The file is too large for the destination file system" error with simple steps.
Solution 1: Formatting FAT32 to NTFS with Windows built-in feature
Formatting is the easiest way for you to convert FAT32 to NTFS. But notice that it will erase all the existing data on the drive. So, it is recommended only when there are no files on your external hard drive or USB flash drive. If there are files existing on your storage device, you can back them up by manually copying or using free backup software in advance. Here's how to do it with Windows built-in format feature.
Step 1: Connect your USB flash drive to the computer.
Step 2: Right-click on the USB drive or external hard drive and click "Format".
Step 3: Change the type to NTFS.
Done!! Now you have fixed the issue "The file is too large for the destination file system" and can successfully copy a file larger than 4GB to the external USB drive or hard drive.
Solution 2: Converting FAT32 to NTFS without data loss
If you want to finish this task in a more convenient way, here's a better solution. Converting FAT32 to NTFS without data loss using the partition tool - EaseUS Partition Master. This popular third-party partition software is an optimal choice. It allows you to fix "The file is too large for the destination file system" issue without formatting as well as data loss.

Step 3. Click "OK" on the pop-up dialog box to continue.

The Bottom Line
Once you understand "the file is too large for the destination file system" is caused by the FAT32 file system, the solution is specific: change the file system.
