question about folders

are the following folders supposed to be there by default: incomplete and sites under my username area? I just dont know what purpose they serve. under the sites folder there are 2 files one called images and one that is index.html. just wondering thanks!

the 'incomplete' folder is because you have probably downloaded something from Limewire. this is the folder all of the incomplete downloads go so as long as you don't have any you can delete it. the sites folder is there by default. I believe this is where you save your files you create in iWeb, I'm not 100% but I'm pretty sure you can delete it with no problems

where is this alleged incomplete folder?

the sites folder is a default folder. if you activate the web-sharing capabilities of your Mac, the apache server program will read the Sites folder as the default home page for your Mac.
