Tip: Use Disk Management to help.

Please make sure the most recent version of Windows ADK is installed. Then you can follow the guide below to create multiple partitions on USB drive:

Step 1. Right-click the partition on the USB drive and select "Shrink Volume" from the context menu. (Tip: you should know that Windows can only shrink a partition that has NTFS or RAW file system. Hence, you need to format the partition to NTFS if it has other file systems.)

Step 3. Now right-click on the unallocated space released just now and then choose "New Simple Volume". Follow the New Simple Volume Wizard and determine the volume size, drive letter, file system, allocation unit size, volume label and click Next > Finish.

Knowing how to partition USB flash drive/thumb drive, how to further manage the already created partitions? Don't worry, MiniTool Partition Wizard makes everything easy. Here we would like to show you some features that can be used frequently.

Format Partition

As USB drives are always taken away and connected to computers with different operating systems, sometimes you may find the USB drive is not accessible on a different PC. Besides, a USB drive may become inaccessible because of the RAW file system and Windows asks you to format it. If these are the cases you encounter, you should consider changing the file system of the USB drive.

But how to change file system when a partition is already created? The easier way we think is to format the hard drive with new file system. But remember formatting will lead to data loss, so you need to transfer important files to a safe location beforehand to avoid data loss.

Tip: you may just format USB drive within Windows. But if you see the "Windows Was Unable to Complete the Format" Error, you had better use MiniTool Partition Wizard instead.

Step 1. Select the USB partition and choose "Format Partition" from the action panel.
Step 2. Drop down the file system list to choose the file system you need before you click OK.
Step 3. When you see the main interface again, press Apply on the toolbar.

Convert between FAT and NTFS

Sometimes you may just want to convert a FAT/FAT32 partition to NTFS because you are going to save individual files larger than 4GB to the USB drive but Windows says "file is too large for the destination file system". MiniTool Partition Wizard helps you do the conversion without data loss. Just select the FAT/FAT32 partition on the USB drive and choose "Convert FAT to NTFS" from the action panel and then click Start button in the pop-up window.

Also, if you use the USB drive on PS3/PS4 to play games, you will find that NTFS is not supported. In this case, you have to convert the NTFS partition to FAT32.

However, you should know this is a paid feature that is available only in the Pro and more advanced editions (view Edition Comparison). Get a copy of the Pro edition if you are interested.

Delete Partition

Another frequently used feature is Delete Partition. In short, if a partition is no longer needed, you can go ahead and delete it. Also, to reparation USB hard drive, you may need to delete the existing partitions and then create new partitions with the desired partition size and file system.
