Is it possible to use a flash drive (transfer files) if an OS is installed on it?

Answer 1

Well, you can throw it in, but while the OS is running, it’s better not to take it out, lol.
You can transfer files to it.

Answer 2

Yes, you can, if it's not in ISO format, to some reasonable file system.

Answer 3

1/ usually on LiveOS, according to the instructions, a directory is provided for storing user files
2/ when transferring, take into account file size restrictions and support for the usb flash file system format on guest OS
