Can I format an external hard drive to FAT32? Check size limitations

An external hard drive larger than 32GB – If your storage device will be used across multiple operating systems, format it as exFAT.

External hard drives larger than 32 GB can be formatted to FAT32, but there are some limitations. First, FAT32 has a maximum file size limit of 4 GB, so any single file larger than this would need to be split into smaller pieces. Otherwise, you'll see the "volume too big for FAT32" error. Additionally, with an increase in the number of files to be stored, larger drives might experience slightly slower data transfer rates. Therefore, it's generally better to format larger external hard drives to exFAT.
