Scenario

Case 1:

“I have a USB drive with important data on it, and try to clone the USB flash drive to another flash drive for the purpose of backup. Cause the data is a little bit large, copy and paste can be a waste of time. Is there any easy and effective method to do this operation?”

Case 2:

“I’d like to copy my USB drive to a newly purchased and bigger Kingston flash drive. The old flash drive was used as bootable device before and I want to upgrade it. I knew that Copy and Paste method won’t help in this situation. I need a recommendation of free USB cloning software which works under Windows. Thanks”
