You need to be careful, since deleting some files can mess up your system. Is this file one you put on your system or a program you know put on the system? Is it being used by anything?

If you know it is safe to delete, perhaps move it to another location, or take ownership.

I am careful, this is a file in a directory i installed of a random software... nothing to do with system and such... tried the "Take ownership" method. didnt work.

Use Safe Mode.

Or add your user account to the permissions with full control rights after taking ownership.
