Can't open fat32

"Hello, I can't open my USB drive on my Windows 10 computer. However, this drive works fine and I can access all the files on my Windows Vista PC. The USB drive is formatted as FAT32. Why can't I open it on Windows 10? Please help."

If you've encountered the "FAT32 can't be opened" issue, then you're in the right place. This article will guide you through why your Windows 10 computer fails to open a FAT32 USB drive and possible solutions to fix it. We'll also recommend a third-party tool - AOMEI Partition Assistant - for formatting FAT32.

Can't open FAT32? Why?

The first reason you might not be able to open a FAT32 formatted drive is that the partition you're trying to use is larger than 32 GB. This is because Microsoft limits the maximum file size on a FAT32 drive to 32 GB. If you try to open a file larger than this, you'll encounter the "Can't Open" error.

Also, if you try to format the partition from File Explorer, you won't see the FAT32 option. On the other hand, if you use Diskpart to format the disk, you will get an error: “The volume is too big for this format.” Secondly, since your primary partition on the removable drive isn't FAT32, you might not be able to open it on a Windows 10 machine.

Since Windows 10 only recognizes the first primary partition, it doesn't allow you to partition it. Lastly, if your removable drive is write-protected, you won't be able to open FAT32 on Windows. This means the drive is read-only and can't be altered through writing or formatting.

Regarding FAT32

FAT32 (File Allocation Table 32) is a file storage system used for devices storing up to 32 GB of data. Introduced in 1977, it is currently supported by all operating systems, including Windows, Mac, and Linux, as well as mobile devices.

Due to its compatibility with various devices, FAT32 is considered more reliable for sharing files between different computers. As such, all SD cards and USB drives are formatted with FAT32. The main drawback of FAT32 is that it doesn't support larger storage drives and doesn't allow individual files larger than 4 GB to be stored.

However, the file system is still compatible with other devices, including:

    • Windows 98
    • Closed-circuit television camera
    • Game console
    • Smartphone
    • Digital camera

FAT32 does not have built-in compression functionality. The file system can handle partitions with a maximum total storage capacity of 16 TB. It's also worth noting that Windows 10 computers cannot format drives with the FAT32 file system. Aside from FAT32, other standard file systems include NTFS and exFAT.

NTFS is suitable for the latest operating systems, while exFAT is best for devices with lower memory and power requirements. The table below compares the three file systems.

FAT32, exFAT, and NTFS Comparison Dialogue

FAT32 exFAT NTFS
- Supported by various devices including Windows, Mac, and Linux - Works well on Windows 10/8/7 computers - Works well on Windows 10/8/7 computers
- First used for Windows 95 devices - First used for Windows XP and Vista - First used for Windows NT devices
- No additional configuration needed on Mac - Requires additional configuration on Mac OS X and Linux - Read-only access on Mac and some versions of Linux
- Maximum partition size is 8 TB, file size limit is 4 GB - No limitations on partition size or file size - No limitations on partition size or file size
- Considered an older file system type, less efficient than NTFS - Seen as a replacement for FAT32, suitable for most devices - Modern file system used by the latest Windows devices
