This is probably 1st time I am posting a question here.
I tried searching few thing here but couldn't able to get anything specific.

1. I wants to delete some large files from windows folder but it's not allowing me. I want to delete those large junk files like audiableair, sprint navigator etc.
2. I think WM5 was allowing to change the setting for call history, Is anyway I can change the setting to say 60 days or longer?

Thanks guys.
