Those are thumbnails dispayed in Sitecore backend.

Do not delete them.

First time Sitecore needs any thumbnail, it extractss one of those files and gets the proper thumbnail with requested size.

E.g. when you open Content Editor and select Home item:

enter image description here

you can see that icon it uses is

You can extract Network.zip from that folder you mentioned and in 16x16 folder (size of the file) you will find home.png icon which is displayed in Content Editor:

  • Do you know why they put them into zip files instead of standard folders?
