Standard chm template creates book icons.
If you want to change to folder
you need to specify it in HHC file by this tag:
<param name="ImageType" value="Folder">
To do it, you need to modify your template. Go to Templates folder and open your template in a text editor. Find the line containing this text:
<param name="Window Styles" value="0x800025">
add the following line after it:
<param name="ImageType" value="Folder">
Save the file. Then just compile your documentation using new template.
