Today to read documents having different extension, a user need to install different application this can open those documents. Let's take an example if a user wants to view a word document than there should be MS Office installed on his/her own PC. In addition, to view PDF file, there must be Adobe PDF Reader installed. Similar is the case with Multimedia files. The authors need to again install different software applications. Now just for viewing all these files, installing all such application would be hectic and cumbersome task as it utilizes many PC resources like hard disk space, CPU memory etc.
