WinAPI way to determine if a file is accessible/private

Question

In win32 c++; is there a way to determine if a folder/file is accessible? You know how if you try to access a certain folder in the C:/Windows directory & you will get a pop

Answer 1

Best thing to do is just try to access it.

You can calculate the access granted by the access control list for a particular user account, but this is quite complicated, and the permission could change after you do the access check. So just open the file and handle access denied errors.
