			You can use TweakEpub (from the makers of Atlantis). It will load an epub and you can then select the file you want to edit. It opens the file in the editor of your choice (mine is Notepad++) and if you are finished, just save. It will update the epub without repacking.

			I've also been using ePubPack for a while now.  I like its simplicity and lack of bloat. Thumbs up. 
		
	
		
		
		
		
		
		
		
		
		
		
	
	I'll try TweakEpub and see whether it works for me.  |

				epubpack archive size
			 
			
			
			I noticed that the archive size created when you rezip an epub is quite a bit larger than the size the archive started as (made from some epub app). How can I fix this?

			The zip library used isn't very efficient. Someone needs to improve it.

 Either your link is incorrect or you've deleted the file. Also, I had to login before I could see that there is a problem downloading.  |

				Windows 8 update?
			 
			
			
			Thanks so much, awx, for this software. I've used it previously on a different computer, but had to buy a new computer with Windows 8 after that one broke. Can you tell me if you have any plans to update ePubPack to work with Windows 8? I would really like to use it again! Thanks!

			AdvanceCOMP ZIP Compression Utility supports recompression with zopfli algorithm with any number of iterations. I am not an expert to say how well it works. However, epubs are smaller after recompression.
