Yesterday, while copying some large files to an external hard drive, I was promptly issued this message by Windows: The file “myfile” is too large for the destination file system. So I wondered to myself what could possibly cause this issue. My external hard drive had tons of free space, so why would I not be able to copy this file over?
Well, the reason for this problem is because my file was 4.3 GB in size and my external hard drive was formatted in FAT32 format. The max file size for FAT32 is 4GB. The max file size for FAT16 is only 2GB! So how do you fix this problem? Well there are two ways you can go about it. You can either split the file into smaller pieces and then copy it to your external hard drive or you can convert the file system to NTFS, where there is no limit on file sizes.
You can read my previous posts on using or HJ-Split to. If you want to go with the second method, read my post on without losing any data.

Now you should be able to copy your large files by either splitting them or converting the hard drive to NTFS! If you have a USB drive, read my post on how to. If you can’t split the file for whatever reason and you don’t want to convert the file system on the drive to NTFS, the only other possible solution is to try and compress the file. Windows 7 and Windows 10 both have built in compression tools, but you can also try third-party tools like 7-Zip, etc. Check out my article that to see if you can get your file shrunk down to a small enough size.
Sep 20, 2017 - File is Too Large for Destination File System on Large USB Key. The USB drive is recognized by Windows, was bought new and was plenty large enough for the files. Mac OS can read NTFS fine but still cannot write to it. Add to that the average file size of a 4K video, which runs at 2GB per minute of.
Password-protect and hide personal files and folders with Folder Guard for Windows 10,8,7, and XP. User rating: 4.7/5 or a free trial. The capacity of your external flash drive or SD card is large: 8GB, 16GB, or more. There is enough free space on the drive. You can copy the smaller files to the external drive just fine. Yet, when you attempt to copy a large file (4GB or larger) to the external drive, Windows gives you an error (such as: There is not enough free space on the drive, or similar.) Does this sound familiar? If you experience such a problem, most probably it’s caused by the fact that your external drive or card is formatted with the.
This type of a file system has a built-in limitation on the size of the files that it may contain. Although the total size of the files that you can copy to a FAT32 drive could be as large as 2TB (or the physical capacity of the drive, whichever is smaller), the size of each individual file may not exceed 4GB. This limitation may sound silly: why would anyone design a system that would not allow for the larger files? The problem is, when the FAT32 file system was designed (that was back in the days of Windows 95), no one anticipated that we would have such large files in use today.
Or, maybe the designers hoped that by the time such large files become common, the use of the FAT32 system would be replaced by the more modern systems. In any case, how to solve the problem of copying the 4GB files? Easy: you need to replace the FAT32 file system on the drive with a more modern one, such as. These newer file systems not have the 4GB file size limitation! Scroll down this page for the instructions on how to change the file system. Which file system is better, NTFS or exFAT?
They both a pretty good, but which one to choose depends on how else you are going to use the external drive or SD card. The NTFS file system is supported by all modern versions of Windows (including such dinosaurs as Windows XP, Windows 2000, and Windows NT), and it also supports many other functions not supported by FAT32: file security, encryption, compression, etc.
However, if you plan to use the external drive with non-Windows devices (such as an Android tablet or a Mac computer), it would not be recognized by such devices out of the box, and you would need to install additional software or tweak their settings quite a bit to make them work with the NTFS drives. The exFAT system is not as advanced as NTFS, but it has more support on the non-Windows platforms. For example, many Android phones and tablets, as well as the recent versions of macOS support exFAT devices pretty well. How to change the drive from FAT32 to NTFS or exFAT format?
Let’s show how to it for NTFS first. There are several ways to go. If the drive or card is empty or contains no important files of yours, the easiest way is to use the Windows Format command to format the drive with the NTFS file system. Specifically: Encrypt and password-protect external drives with USBCrypt software for Windows 10,8,7, and XP. User rating: 4.7/5 or a free trial. Attach the external flash drive to the computer, wait for Windows to recognize it and assign a new drive letter to it. Open the Computer folder and locate the drive letter assigned to the flash drive you want to format with NTFS (in the example below, it’s drive F:) 3.
Before continuing, open the drive in a window and make sure it’s empty or does not contain any important files, because after you format a drive, all information that was on it will be erased! If there are files on the drive that you want to keep, take this opportunity to copy them over to the hard drive or some other drive. If you are sure that the external drive contains no important files of yours, go back to the Computer folder, and right click on the icon of the external drive: 5. Select Format from the menu, and then choose the formatting options: 6. Make sure to select NTFS in the File System drop-down list.

That’s what determines the kind of a file system that the drive should have. Also, you may want to select the Quick Format option, which should speed up the formatting process quite considerably. Press Start, and Windows should warn you once again about erasing any existing information on the drive (see step 3 above). Again, if you are sure the drive does not contain any irreplaceable documents, confirm that you want to proceed with the formatting: 8. If you’ve selected the Quick format option, the formatting should take no longer than a minute or two. As a result, you should have the same drive, but now it should have the NTFS files system on it.
Now you should be able to copy the files larger than 4GB to the drive just fine. In addition to formatting a drive with the NTFS file system, Windows also offers a way to convert a FAT32 drive to NTFS.
The difference is that the conversion process would keep the existing files on the drive. See Windows Help and Support of your computer for the instructions on how to do the conversion. What if I want to use exFAT instead of NTFS? The steps to change to exFAT are the same as for NTFS, you only need to select exFAT in the dropdown box instead of NTFS. Encrypt and password-protect external drives with USBCrypt software for Windows 10,8,7, and XP. User rating: 4.7/5 or a free trial.
Our encryption software can create a NTFS- or exFAT-formatted Virtual Encrypted Disk even if the host drive is formatted with FAT32. This suggests yet another solution: instead of formatting the host disk with NTFS, you can instead use USBCrypt to create a NTFS-formatted Virtual Encrypted Disk. If you do that, then in addition to breaking the 4GB file size barrier, you would also get the strong security and password protection for files you put inside of the Virtual Encrypted Disk. See the for more information or to download a free 30-day trial.
If you only need to transfer a large file from one computer to another, you can get by with the FAT format if you use a file splitter utility, like the one included in our file manager. Using its, you can split a large file into smaller chunks (say, 2GB each). Such chunks can be put on a FAT-formatted drive without a problem. Then, on the destination computer, use the command to combine the chunks together into the original file. Of course, if you want to open the file directly from the external FAT drive, this won’t help you, but just to transfer the file between Windows computers should work fine.
