USB Flash Drive
There are two cases you may encounter when using the drive. The one is related to resize the USB partitions, and the other ties to increase the USB storage.
In general, it’s OK to create partitions on the USB flash drive. Unfortunately, because of the limitation of Microsoft, you can only see one partition of USB flash drive in Windows. It means you can adjust one partition on Windows.
If the USB is indeed partitioned and can not access other partitions, you can use the partition tool to delete other partitions and extend the first partition. In the end, the entire USB flash drive has only one partition, and you can change this partition. You can resize the USB partition through the EaseUS Partition Master.
What makes us frustrated is that USB often shows insufficient space. Here we introduce some methods to give you a hand on how to increase USB storage. Before using either method, you’d better to back up important files first.

Deleting files can not always work for the necessary data, so we are going to introduce some available methods for you. If your device is occupied with important files, in the former part, you can use the compress or delete function to free it up. But if it’s filled with unnecessary files, the format method in the latter part may be better.
Part 1. Increase USB storage while preserving data
1. Compress file size to increase USB storage
Compressing file is to compress one or more files so that its file size is smaller than the original file size. After compressing your folder, your USB’s downloading and transferring speed will be faster.
Step 1: Insert the USB to the computer.
Step 2: Right-click the file or folder and choose “send to”, choose “Compressed (zipped) folder”
You also can use file compression software, like WinZip or WinRAR to compress data.
2. Delete unwanted hidden files
Step 1. Open Control Panel > Open File Explorer Options
Step 2. Click on View > Click on Show hidden files, folders, and drives
Step 3. Then you can start deleting the hidden files on the drive.
Part 2. Free up space without retaining data (Re-format USB flash drive with partition software)
You can free up space by Re-formatting the USB flash drive. But it will wipe all data of your USB. Before formatting the flash drive, we recommend back up all data at first.
Step 1. Select the USB drive to format.
Connect the USB drive or pen drive to your computer. Download and launch EaseUS partition software. Right-click the USB drive you intend to format and choose "Format".
Step 2. Set the drive letter and file system on USB.
Assign a new partition label, file system (NTFS/FAT32/EXT2/EXT3/EXT4/exFAT), and cluster size to the selected partition, then click "OK".
Step 3. Check "OK" to confirm formatting USB.
Click "OK" if you see the Warning window. If you have important data on it, back up the data in advance.
Step 4. Apply the changes.
Click the "Execute operation" button first, and then click "Apply" to format the USB drive.
