[SOLVED] How to restore the full capacity of my USB flash drive?

[TheFlash1300]

Hello. Today, i used Etcher to install .iso file (Windows 7) on my USB flash drive, so i can use the USB flash drive as a source of Windows 7, so i can use Windows 7, without having to install it on the SSD of my computer.

Before i did that, my USB had 64GB of space. After i did it, my USB now has 10,6GB of space. I want to remove the OS from the USB, and restore the USB to its full capacity. How to restore the full capacity? I tried formatting it by right-click, and selecting "Format", but nothing happened. I tried with the option "Quick format" and without that option, but nothing changes.

The OS i use on my laptop is Windows 10.

Can someone help me, please...

Commandline function diskpart, and the clean command. Then reformat.

Be absolutely sure what device you are accessing. 'clean' is a one way thing. There is no coming back if you wipe the wrong drive.
