This blog adds large hidden bitmap files to the zips, making them seem larger than they actually are.
Take the first file on the site for example. It contains a hidden bitmap file named "40librarymusic.eklablog.com.bmp".
Why did they add a 40 MB hidden bitmap file?
The actual zip size should be 67 MB, not over 100 MB.
You wouldn't notice the files unless you turn on viewing hidden files on your computer.
The only reason I can think of for doing this is to make people think the zips are higher quality than they actually are.
