[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.
