This article includes step-by-step guide to resize exFAT partition without losing data in Windows 10/8/7. You can follow this guide to resize exFAT, FAT32 or NTFS partitions easily.
overview on exFAT file system
exFAT, Extended File Allocation Table, is one file system type introduced by Microsoft in 2006 and optimized for flash memory such as SD cards and USB flash drives. Microsoft introduced exFAT file system with Vista SP1, becoming the successor to FAT32 file system.
By default Windows operating system can only format disk up to 32GB only. When the drive being formatted is bigger than 32GB, FAT32 is no longer efficient. What’s more, the maximum file size of a single file on a FAT32 drive is 4GB, which is far from enough in many cases. Thus FAT32 partition is limited with file size it can hold.
exFAT has very large file size and partition size limitation. It allows individual files larger than 4GB, which facilitates a lot. For example, if a long continuous recording of video is larger than 4GB, digital camera using FA32 will break the file into several segments. Here a memory card using exFAT file system will be very useful.
Besides, exFAT owns better compatibility than NTFS. MAC OS X provides read-only support for NTFS, while it is fully support exFAT, including read and write. exFAT can also be accessed under Linux once appropriate software is installed. Therefore, it works with all versions of Windows and recent version Mac OS X.
