Stream Locker

Having a quick way to lock a file, preventing it from being read or modified, can be very helpful during software development or when running tests. Time saved while performing these tasks adds up at the end of the day, which is why relying on a specialized utility can be a good idea.

Stream Locker is a small, open-source program that provides you with a very simple way to get the job done – it allows you to put a Read, Write or ReadWrite stream lock on a file from an intuitive user interface.

You can start using this program instantly, as it comes in the form of a single executable file and doesn’t require you to install anything on your PC beforehand. Of course, you can launch it from any location without having to worry about anything being left behind.

Stream Locker features a minimalistic and intuitive user interface, which only includes a few buttons and also shows the path of the file you have opened. The application also offers support for drag and drop.

Once you’ve opened a file, you can choose to place a Read, Write or ReadWrite lock on it, making it impossible for its contents to be accessed or modified. If a user attempts to perform these actions, the system will show that the file is currently being used by another process.

Unlocking a file is just as simple – you only need to click the unlock button in the main window, although closing the program will have the same effect.

Stream Locker is a very simple piece of software, and it can save you a lot of time if you often need to lock files when working on various projects. It is very intuitive, and it can be put to use right after being downloaded.
