Thanks Vinay, I think you are right. I thought about it but then server will have to manage huge set of folders. I also thought that what if we give a unique ID for each file for each user. So, when user wants to access his file the code should first checks if the unique ID and the username is matched. I just have a rough idea. If someone got my points please explain it to me. Am not sure this may be a solution.
Guys plz help me???? Best,
