Yes, you can operate it just as a local hard disk.

£´£©When I unplug the USB Flash Disk after the computer indicates accomplishment of copy process, it prompts that files have not been copied completely yet, Why?
Since the operating system provides buffer space for data storage, the rate of progress does not equal to the real accomplishment of data copy. User should notice the LED indicator.
