More specifically, can you tell me the path of the folder you're trying to change? Because it's sounding more and more like a security problem than a read-only problem you're having.
Unless it's your normal users folders, such as "Documents", "Pictures", etc. you shouldn't mess with them unless you know what you're doing. Those folders that are hidden by default should remain so, and are hidden from view for a reason, not the least of which is system and application stability.
