Why Can't Copy, Move or Transfer File Over 4GB to FAT32

'Recently I encountered a strange problem. I plugged my new 32 GB USB flash drive into my computer, trying to transfer some files. Files like MP3s and documents were all transferred quickly except some larger DVD ISO files and video files. I got the error 'The file is too large for the destination file system'. Then the transfer failed. The biggest file is about 5GB and the file system of my USB is FAT32. Does anyone know how to copy large files over 4GB to a USB flash drive?'

To figure out the reason why some large files transfer between the USB drive and computer failed, it's necessary to know the FAT32 file system as well as the FAT32 file size limit in Windows 10/8/7.

• What's FAT32?

File systems are ways of organizing storage on devices such as hard drives, SSDs, USB sticks, microSD cards, and so on. For FAT32, it is one of the most popular file systems ever used on smartphones, tablets, digital cameras, game consoles, surveillance cameras, and so on. Moreover, it's also cross-compatible with almost all operating systems from Windows to macOS and Linux.

• What's the maximum file size for FAT32?

4GB. Individual files on a FAT32 drive can't be over 4 GB in size—that's the maximum. A FAT32 partition must also be less than 8 TB, which admittedly is less of a limitation unless you're using super-high-capacity drives.

Hence, due to the FAT32 file size limit, it's not possible to manage (copy, move, save or transfer) a 4GB file on any drive formatted with the FAT32 file system. The error message 'The file is too large for the destination file system' also suggests that you're trying to copy a more than 4GB file to a FAT32 storage drive and that's not going to happen.

How to Transfer Files Larger than 4GB to FAT32 with or Without Formatting

You must try to break the FAT32 file size limit to be able to save some extremely large files. The only solution is to change the file system to the other Windows-compatible file systems, usually NTFS. The conversion is easy, and there are four methods in total.

* The way of formatting a disk in Windows Explorer and Windows Disk Management will erase data completely, you must back up all important files in advance. If you are reluctant to make backups, pick the other two methods of using commands and third-party EaseUS partition manager software, which are not about formatting but a simple conversion with no data loss.

Method 1. Reformat FAT32 in Windows File Explorer

Disk formatting allows you to make changes to the file system on a device. So when you want to change the file system from FAT32 to NTFS to be able to transfer a more than 4GB file on a USB flash drive or a memory card, Windows File Explorer in Windows 10/8/7 is a convenient option because it's built-in the operating system and you don't have to download it.

Note: Back up data before formatting FAT32 to NTFS

Step 1. Press Windows + E keys to bring up the Windows Explorer.

Step 2. Right-click on the connected USB drive or SD card and choose Format.

Step 3. From the File system drop-down list, choose NTFS, and click Start.

Method 2. Reformat FAT32 in Windows Disk Management

Windows Disk management is the other default Windows disk formatting program that enables you to format a FAT32 USB drive or SD card to NTFS. You can not only use the Disk Management to solve the problem of being unable to copy files bigger than 4GB to FAT32 but also format a RAW drive to a recognized file system by Windows.

Note: Back up data before formatting FAT32 to NTFS

Step 1. Navigate to This PC/My Computer > Manage > Disk Management.

Step 2. Right-click on the connected USB drive or SD card and choose Format.

Step 3. Choose NTFS as the target file system and click OK.

Method 3. Change FAT32 to NTFS in Windows Command Prompt Without Formatting

Though it's not going to format the drive and cause data loss, the Windows command prompt way of fixing the file too large for USB problem is kind of tricky and not so recommended to computer novices. If you're not familiar with the basic command lines, or perhaps you cannot run the cmd with the administrator privilege, turn to the third-party easy solution.

Step 1. Press Windows + R keys to bring up the Run box, type cmd and hit Enter.

Step 2. On the Windows Command Prompt windows, type the command convert [drive letter]: /fs: [file system] and hit Enter.

For Example: convert G: /fs: ntfs.

Method 4. Convert FAT32 to NTFS in EaseUS Partition Master Without Formatting

Normally, users can use Windows Disk Management or Windows File Explorer to format USB drive or SD card from FAT32 to NTFS, but it will delete all the data on the drive. Nevertheless, the convert X: /fs: ntfs command can protect the data, it's not friendly to average computer users.

To make up for the shortcomings of the former three methods of changing the FAT32 file system to NTFS, which is either erasing data or too risky to run the commands, here comes the almighty free partition software - EaseUS Partition Master. On the one hand, it's able to convert a FAT32 drive to NTFS without formatting. On the other hand, the conversion process is so simple and it's only a matter of a few clicks.

Step 1: Install and launch EaseUS Partition Master on your computer.

Step 2: Select a FAT32 partition, right-click on it and select 'Convert to NTFS'. If you need to convert a storage device such as SD card or USB flash drive to NTFS, insert it into your PC first and repeat the previous operation.

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

Step 4: Go to the upper left corner, click the 'Execute 1 Operation' button and you will see the operation details. Click 'Apply' and 'Finish' when the process completes.

How to format internal and/or external drive to work properly on Mac and Windows computers?

External data storage devices such as USB flash drives, external Hard Disk Drives (HDDs), and Solid State Drives (SSDs) provide one of the easiest ways to transfer files between separate computers without accessing the Internet. This option is often used when attempting to move very large files. The method is also chosen by people who work with media data that imposes various limitations and automatic optimizations when transferring via Internet. Despite the advantages of using external data storage to transfer content, some experienced users encounter problems caused by the difference between operating systems. This article addresses these issues.

A common issue discussed by users within various technical support forums is that of USB flash drives not working on their computers. This is a cross-platform problem that Windows and macOS users often experience. For example, a photographer may provide you with a USB flash drive with stored photos and videos from your birthday party, but you cannot access them on your system. This is the result of differences between operating systems on computers. Windows and macOS use separate file system formats. PCs with Windows operating systems use New Technology File System (NTFS) while Macs with macOS operating systems use Hierarchical File System (HFS+). By default, USB flash drives and external storage are formatted with the NTFS file system - this works flawlessly on PCs, while Mac computers are able to read data in the format, but struggle to write using this type of storage. Fortunately, there is a simple solution: format your external storage with the File Allocation Table (FAT32) or Extended File Allocation Table (exFAT) file system. In this article, we describe the differences between these two file systems and how to format external storage using a Mac computer.

Which file system to choose - FAT32 or exFAT?

As mentioned above, both file systems are compatible with Windows or macOS/OS X operating systems. Naturally, the question is: which should you choose? To make the choice easier, we describe both file systems and their features below.

Starting with FAT32 [on a Mac, known as MS-DOS (FAT)], this file system is fully compatible with all versions of Windows and Mac operating systems. Therefore, even the oldest versions of operating systems such as Windows XP SP1 and OS x 10.5 Leopard are compatible. As well as computers, the FAT32 file system is supported by PlayStation 3, Xbox 360, and most cameras. This particular file system does contain file size restrictions. For example, the maximum size of supported files is 4GB (you cannot write files larger than 4GB). Also, you cannot create a startup drive for Mac computers within storage media that uses the FAT32 file system. If, however, you are not planning to use external storage to transfer large files or create any executable partitions (such as a Mac startup drive) the FAT32 file system might be an option, since this format is supported in all versions of the operating system.

exFAT is a newer file system format and has the biggest advantage when compared with FAT32: there are no restrictions on file or partition sizes stored. Therefore, you can write a file of, for example, 1TB size and create partitions of 5TB within the device. Despite this improvement of available data size, some older versions of operating systems are no longer compatible with this file system format. The oldest versions of operating systems compatible with exFAT are listed below:

• Mac OS X Snow Leopard 10.6.5 or later
• OS X Lion
• Windows XP SP2 or later (with an additional update for exFAT support)
• Windows Vista SP1 or later
• Windows 7

Unfortunately, as well as some old versions of operating systems, the exFAT file system format is not supported by various cameras, video games consoles, and other devices able to read and/or write to external storage. If you will be using a USB flash drive or external storage device with any of these, the required format is FAT32. Otherwise, if the device is to be used only with computers with modern versions of operating systems, the recommended format is exFAT.

Format the drive with Mac computer

Firstly, bear in mind that formatting the drive will erase all content stored on it. Mac computers are capable of formatting any storage device (internal or external) such as HDD/SSD, USB flash drive, and external storage. Even if the Mac is unable to mount the storage, following this method will enable you to format the storage. Begin by connecting the storage device to your Mac, and then launch Disk Utility using Spotlight. Simply use the keyboard shortcut of Command and Spacebar, type Disk Utility, and then press return. Alternatively, open Finder and go to Applications, open Utilities, and then launch Disk Utility. Select the drive you wish to format from the list in the left sidebar of the Disk Utility window.

Then click the Erase button at the top of the window, in the new pop-up window, and type the name of drive. Then click the drop-down menu beside Format and select MS-DOS (FAT) - the FAT32 file format - or exFAT. These formats are described above.

If you are not planning to use this drive as the Windows startup disk or use it with the oldest version of the operating system, do not change the Scheme. Select Master Boot Record.

Finally, when all preferences are set, click the Erase button. The formatting process duration depends on size and type of the drive. A hard disk drive will take longer to format than a flash drive. NOTE: formatting will erase all existing data on the drive.
