Loading file in separate window?


this is something that is weird to me.
but any time that i double click on a file on my desktop [or anywhere], it opens up on my current project [which is not linked to any other files]

how can i get it to open a new window instead. i know this has come up and annoyed people. but i find it annoying it puts it in the window im working on.
plus i cant just click and drag off of the window, because then that copies it onto the desktop in a txt file

or how about that if you want it to open on a new window, you can click and drag the file/folder on the icon to open on a new window?

but ive not found any setting to allow me to open in a new window
