The .scr file extension is used for a system file format that was developed by Microsoft. These SCR files are screensaver files that are used by Windows for energy-saving purposes.These Windows screensavers were originally created to prolong the life of CRT and plasma display monitors. If a screensaver has been set by the user through the display properties of Windows, then the system will automatically activate the user's chosen screensaver when the Windows computer has been idle for a certain time. This is performed so as to minimize the power consumption levels of these display devices.These SCR files also allow users to secure the Windows desktop. A Windows screensaver can be configured to be protected by a password. Other options like setting a fixed number of idle minutes before the chosen screensaver is activated are available through the display properties of Windows.It's best to leave these .scr files alone. These system files do not contain human readable data and are automatically activated by Windows.
