Keith, when you publish a site with n pages, you will get n html files and one _xar_files folder. The html files are your content and the folder are the assets that support their presentation.
Your issue is, unfortunately, much deeper.

At some point you probably decided to make an on-line backup. You now have a clutch of published websites with some with a sub-folder created with just a space (%20).

I have not dug out all the htm files but this gives you an idea of the duplication;

I've found your site and page naming convention rather odd.

The safest approach is to open all the design files that you believe are the current ones and set up a local file structure that will be reflected in your publish webspace:

..blog/2010/ - call the design file 2010 Blog.xar with first page index, second - index-a, third - index-b, ...
..blog/2011/
..blog/2012/
..blog/2013/
..blog/2014/
..blog/2015/
..blog/2016/
..blog/2017/
..blog/2018/
..blog/2019/
..blog/2020/
..blog/2021/
..blog/2022/
..blog/2023/
..blog/2024/ - call the design file 2024 Blog.xar with first page index, second - index-a, third - index-b, ...

and
..orientdiary/part1/ - call the design file Orient Diary - Part 1.xar with first page index, second - index-a, third - index-b, ...
..orientdiary/part2/
..orientdiary/part3/
..orientdiary/part4/ - call the design file Orient Diary - Part 4.xar with first page index, second - index-a, third - index-b, ...
