How to Resize exFAT Partition (Extend/Shrink exFAT Volume)

Do you have trouble extending or shrinking an exFAT volume in Disk Management? Is the button greyed out? Do not worry! This page will show you how to resize the exFAT partition with ease.

ExFAT is primarily used for flash memory devices such as USB flash drives, and SD cards (especially SDXC and SDUC cards larger than 32 GB). However, many users are facing the problem that Windows Disk Management doesn't support resizing an exFAT partition. Neither you can extend it or shrink it since the options are greyed out for certain reasons.

But worry not. This page from EaseUS will offer you a practical and detailed guide on how to resize exFAT partition.

Why Is Extend/Shrink exFAT Volume Option Greyed Out

There are a few common reasons why the Extend and Shrink Volume is greyed out when you try to resize the exFAT partition:

• File System Limitation: Windows Disk Management doesn't support extending and shrinking exFAT partitions. It only supports resizing NTFS partitions.
• Lack of Unallocated Space: The "Extend Volume" option will be greyed out if there's no contiguous unallocated space adjacent to the partition you wish to extend.
• Unmovable Files: If there are unmovable files like system files, virtual memory, or locked files at the end of the partition, Windows cannot shrink the volume.
• Fragmentation: Disk fragmentation can prevent users from shrinking a volume. You can use Disk Defragmenter to clean up your drives.

How to Resize exFAT Partition - 3 Steps

Since Disk Management doesn't support resizing exFAT volume directly, the best option is to format it to NTFS and then resize it. To avoid other issues like unmovable files or non-adjacent unallocated space that might also prevent you from shrink or extend the exFAT partition, the best choice is to resort to EaseUS Partition Master.

Stage 1. Back up your data

If you have any important files on the exFAT partition, create a backup for them before further operation because the format process will delete all data on the drive. If not, you can skip stage 1 and go to the next part.

Stage 2. Format exFAT partition to NTFS

Due to Windows doesn't allow users to resize an exFAT volume, the first step is to format the exFAT partition to NTFS so that you can then shrink or extend it later as you wish.

Step 1. Run EaseUS Partition Master, right-click the hard drive partition you intend to format and choose "Format".

Step 2. In the new window, set the Partition label, File system (NTFS/FAT32/EXT2/EXT3/EXT4/exFAT), and Cluster size for the partition to be formatted, then click "OK".

Step 3. Then you will see a warning window, click "Yes" in it to continue.

Step 4. Click the "Execute 1 Task(s)" button to review the changes, then click "Apply" to start formatting the partition on your hard drive.

Stage 3. Resize the NTFS partition

Now the partition is formatted to the NTFS file system, which is highly compatible with Windows, you can resize it using EaseUS Partition Master without obstacle.

Step 1: Locate and select the target drive/partition

Launch EaseUS Partition Master and go to Partition Manager, select the target drive/partition to adjust its size, right-click on it and choose "Resize/Move".

Step 2: Resize or move the partition

1.To shrink the partition, simply drag one of its ends to free up unallocated space. Once done, click "OK". 

2. To extend the partition, make sure that there is unallocated space aside (if there isn't, follow the above steps to create some). In the same way, drag your mouse into the unallocated space. Click "OK".

3. To move a partition position, you need to leave unallocated space next to the target partition. If no, free up some unallocated space first.

Right-click the target partition, select "Reize/Move". Then drag the whole partition leftward or rightward to adjust its position. Click "OK" to confirm. 

Step 3: Confirm the result and apply changes

At this step, you will see the new disk partition information & diagram.

To save changes, click the "Execute Task" button and then "Apply".

After the process, you can reformat it to exFAT and then restore all the data you just backed up if you have. Or, just keep it as NTFS for better compatibility and less hassle.
