If you wanna do that without any plug-ins you can use gmail or other emails. Just compose a letter(of course you can leave it empty) and attach the html files then send them to yourself. Check this email in “Inbox” then you can open the attached email files in html form. if it doesn't work, you can try some converter softwares which i think is also good to use. i can give you some advices in converting email to html because i always do such a work. i always turn to some third party software which contains the function of converting pdf to many other formats . this sdk can do email to html conversion in c# ,net. vb, etc. as for ppt, i know some softwares are professional in such conversion , you can search on google. good luck. www.rasteredge.com/.../
