				Multiple authors - how does Calibre decide the folder structure?
			 
			
			
			Mostly out of curiosity. I don't intend to go tampering around with the folder structure. 
		
	
		
		
		
		
		
		
		
		
		
		
		
			When fixing up the metadata of books in PDF format, when I add an extra author sometimes I have to close the file because Calibre wants to move the book to a new location. But sometimes it doesn't. (Related: Does anyone know of a PDF viewer that doesn't lock the stupid files when they're open?) Last edited by ownedbycats; 08-30-2020 at 10:37 PM.  |

			Thank you 
		
	
		
		
		
		
		
		
		
		
		
		
	
	Aside from messing about with custom columns, is there any way to set the 'main' author? I'd assume no  |

			Ok I figured that out now.  
		
	
		
		
		
		
		
		
		
		
		
		
		
			  Thanks. Aside from manually re-typing, is there a way to rearrange authors?EDIT: I found the "edit authors" (it's a little hidden in the context menu). It makes the author sort column turn red though until I fix it. Is that supposed to happen? Last edited by ownedbycats; 08-31-2020 at 06:30 PM.  |

			Just click the right arrow to auto-regenerate the author sort.
