Yes, i mean when i try to install in an existing directory (which contains
previous installation). The problem is that i have one plugin renamed and when
i simply install into that dir, old file is not rewritten/deleted and i get 2
copies of same plugin. I want to remove all contents of the directory i install
to before writing new files. Is that possible?
Yes, i can remove that file manually using script, but it's not the best idea
as i think.
