How To Deny Access To Files Or Folders In Windows Vista

Data security is indispensable irrespective of how and where we work. Today’s age is of computers, and therefore, it is obvious that almost all of us work on PCs or laptops. Although these gadgets are always at the risk of unauthorized access when on network, we yet prefer to work on them. Well, a straightforward answer as to why we still prefer to work on PCs or laptops is the proactive approach of the operating system towards securing data.

Here, I am not talking of an antivirus program or scanning software, but I am referring to the embedded ability of the operating system to avert unauthorized access and illicit exposure of private files and folders. Keeping this in mind, we shall now explore this ability of Windows Vista.

Problem: Fear Of Illicit Access To Private Folders

Consider a scenario where you have set up a small network at your home, which consists of three to four PCs including your laptop. Now, you use this laptop running Windows Vista to create and store some official documents that are related to a crucial project of your company.

You also use the laptop for creating a monthly study schedule for your kids. However, many times, you have to give your laptop to the kids, as they love playing games and browsing Internet on it. Therefore, you want to make sure that they do not access these files intentionally or unintentionally. So, what is the solution?

Solution: Deny Access To The Folders Storing Vital Files

It is obvious that the documents in the above scenario are crucial and private as well. Therefore, to secure them, an ideal solution would be to deny access to these files by disabling the access to the folders storing them. Fortunately, Windows Vista allows you to deny access to files and folders in such a way that only you or an administrator can access them. This means you can deny access to selected users.
