I have created a web site with 5 similar pages. How should my files be organized -

I have ended up with 5 html files, but I have also ended up with 5 separate folders with items relating to each page.
I had some problems with missing images when I published my web site, so I' saved as' and exported to a new folder, but only ended up with the 5 html files and 1 folder this time?

I also exported using a different icon in the program and had a duplicate of each html folder. They weren't renamed but seemed identical when looking at their properties.

Can anybody help me out please.
