Do you want to know how to resize USB partition on Windows 11 without losing data? You can do it with three methods including Disk Management, Command Prompt and free USB partition resize software.
USB is the most popular data storage device in people’s life. Thanks to its portability and safety, many users choose it to store important data, including files, images and videos.
Generally, people expect to resize USB partitions on Windows 11/10/8/7 for two reasons:
1. Resize a USB partition in Windows 11 Partitioning a USB flash disk is generally acceptable. Unfortunately, Microsoft's restriction allows you to see just one partition of a USB flash drive in Windows. It indicates that you may change one partition on Windows. If the USB is partitioned and cannot access other partitions, you can use the partition tool to erase them and expand the primary partition. Finally, the USB flash drive only has one partition, which you may adjust.
2. Free up or extend partition What frustrates us is that USB frequently indicates inadequate space. Here are several strategies to help you boost your USB storage. Before utilizing either approach, you should back up crucial files.
Therefore, extending or shrinking the USB partitions is necessary. In this tutorial, I will provide you with two ways to resize the USB partition on Windows 11, including Windows built-in tool Disk Management and a free Windows USB partition tool on Windows 11.
Disk Management is a built-in tool that can help you resize a USB drive with simple steps, you can refer to the following steps.
Warning: Due to the limitations of Windows, Disk Management didn’t support resizing a USB partition. However, users can use Disk Management to extend or shrink partitions since Windows 10 1703 with ADK installed. If you can't resize the Windows partition USB disk with Disk Management, please skip this method.
● Shrink a USB partition
Step 1. Press and hold the "Windows + R" together, then input “diskmgmt.msc” in the window popped.
Step 2. Right-click the partition you want to shrink and select "Shrink Volume".
Step 3. Input the amount of space you want to shrink and click "Shrink".
Tips: ✎ If you ignore unmovable files at the end of the partition you want to shrink, you can't resize the windows partition USB disk with this tool. ✎ The partition must be NTFS or RAW. (Disk Management only supports shrinking or expanding partitions in NTFS and RAW formats. If the USB partition is the other file systems, Shrink/Extend Volume will be greyed out. You can convert the USB to NTFS first and try again.)
● Extend a partition
Step 1. Open Disk Management as the step mentioned above.
Step 2. Right-click the partition you decide to extend and select "Extend Volume".
Step 3. Follow the guidance ejected to complete the rest steps.
Tip: Unallocated space on the USB must be adjacent to the partition which will be extended, or Extend Volume will be greyed out.
If you can’t use Disk Management to resize the USB partition, then you can try AOMEI Partition Assistant Standard. This is a USB partition resize tool for free download on Windows 11, 10, 8, 7, XP, and Vista.
