Performance difference extracting and copying in Asp.Net website with C#

I have almost 100 website that will update in a condition, I have a winzip archive that contains the files that replaces those websites. I want to know that

1. I can extract that files 开发者_Python百科in a folder and then copy them to all 100 websites folders
2. I can extract the archive directly to 100 websites folders

which one is better in performance and less prone to errors.

Possibly better solution (seeing as your source code is the same in each case):

Have your source code in one place on the system and point all the different web sites to the same physical folder.
