Note:

In order to ensure a smooth and successful operation process and data safe, you may check the tips below before resizing/moving your partition:

1. Close all the other applications including the antivirus and firewall when running the software.

2. Please keep 5~10% free space as our product needs some space for data exchanging during resizing.

3. In order to ensure data safe, you'd better backup your data with backup software to a safe place before resizing, such as, EaseUS Todo backup.

4. If there is lots of data on the partition, it will take a long time to resize it. Please do not shut down or restart your computer manually.

5. If there is much data on the involved partitions, the resizing would take more time. In this case, we suggest you do the operations step by step. Apply the operations one by one.
