I'm not clear on this, can i download Libre portable to USB and download to my PC?

If I download Libre to a USB does Libre get stored on my PC somewhere too. And if I download Libre on my PC also, will there be two stored Libre on my PC?

If you install it on the usb, nothing is installed on your pc. There shouldn’t be any problem to have installed in both.

In addition: LibreOffice Portable versions

Thank you for your answer.
