Inside LV you can open it and use Save As... to save wherever you want: in a separate directory as a standalone VI or in another LLB. Make sure to check the Make a Copy checkbox at the bottom of the dialog window if you don't want to chain the new location of the VI to all its callers (this could cause 'VI not found' errors in case you move after that VI outside LV or delete it).
I don't know of any mean to do the same outside LV, in case this is your actual question.
