If you’ve ever tried to format an external hard drive larger than 32GB to FAT32 in Windows, you will have seen that your operating system doesn’t allow you to do it. There are various reasons as to why it does so, but if your particular situation requires you to use FAT32, you need to find a way.

FAT32 is actually a great file system and it was widely used until people started to hit its limits. One of the limits with this file system is that it doesn’t let you store a single file larger than 4GB. People who wanted to store files larger than this size moved on to other formats such as NTFS that allows really large files to be stored on your hard drive.

    The format is still in use though and there are even situations where this is the only format that works. For instance, some of the modern video doorbells you buy require your storage devices to be in the FAT32 format.
