Summary: This article tells how to format a USB flash drive on Windows 10/8/7 and Mac when you want to reformat a new or second-hand removable storage device to make sure it doesn’t contain any malicious files or fix the logical errors.


What is Formatting?

Formatting is the fastest way to prepare the USB flash drive for initial use. It wipes all the data stored on your flash drive and allows full use of the storage capacity. Meanwhile, it also creates a filing system that can help organize your data on Windows or Mac.

Which File System Should I Choose for a USB Flash Drive?

We can’t talk about formatting without talking about file system as it differs when we are using the different computers; the common file systems are FAT32, exFAT, and NTFS for Windows, APFS, HFS+, and exFAT for macOS, here we will only talk about the most common file systems when formatting a USB flash drive:

  • FAT32: It’s compatible with all major operating systems and uses less memory usage. But it cannot handle single files larger than 4GB and has a limited partition size (up to 32GB).
  • NTFS: It can create partitions larger than 32GB and read/write files larger than 4GB. Besides, it supports on-the-fly file encryption. The disadvantage is that the Mac computer can only read the data from the NTFS drive.
  • exFAT: It provides an unlimited file and partition size. It serves no matter the Windows or Mac users who want to work with files larger than 4GB.

We strongly recommend that you use exFAT, which is considered the best choice for both Windows and Mac computers, whereas the exFAT file system works better than FAT32 and can handle the file size up to 16GB.
