I am having many files in my Windows phone. Many of them are just useless and that is the reason that I want to delete them from my phone but I am not able to do that. Whenever I try to delete any folder from there then it shows me the message that says that cannot delete files access denied. Can you tell me that what is the problem that? It is consuming more space in my computer and I want to free the memory from my computer. I will be thankful for all the replies.
