What is an SCR file?
An SCR file is a screen saver file used by Microsoft Windows. It contains a graphic, animation, slide show, or video that you can use as a Windows screensaver. SCR files are typically stored in Windows's main directory.
Screen savers were originally created to prevent CRT and plasma computer monitors from suffering screen burn, a condition that occurs when the screen shows the same image for too long. While most modern monitors do not suffer from screen burn, screen savers are still used for security purposes (to hide a user's screen and require a login before resuming work) and to show a user's style.
How to open an SCR file
To use an SCR file as your Windows screensaver:
- Move the SCR file to your main Windows directory. For example, in Windows 10, move your file to the (C:)\Windows\System32 directory.
- In the Windows search bar, type "screen saver." Select the Change screen saver option from the search results.
- The Screen Saver Settings window appears. From the Screen saver dropdown menu, select your SCR file. Customize the remainder of your screen saver settings, and then click Apply.
Because SCR files may also be executable scripts, you should not open an SCR file or use it as a screen saver if you cannot verify its legitimacy or source. SCR files obtained from outside Windows have been known to contain viruses and other malware.
