Screensaver is a program that starts when a computer is idle for a long time. Its function is to protect the display screen and prevent the phenomenon of "screen burning" caused by staying on the same screen for a long time by displaying animations, images, and other forms when the computer is idle.


Screen saver programs first appeared in the late 1980s, when CRT monitors had a "burn out" problem, where staying on the same screen for a long time would cause the pixels on the monitor screen to be excessively activated, resulting in residual shadows and affecting the display effect. To solve this problem, computer scientists have developed screen saver programs that display animations, images, and other forms of animation during prolonged idle time, enabling even activation of pixels on the screen, thereby reducing the occurrence of "screen burning" phenomenon。


Screen saver programs typically include various forms of animation and images, such as scrolling text, graphics, slides, etc. Users can choose different screen saver programs according to their preferences. In addition to preventing screen burning, screen saver programs can also increase the fun of the computer and improve the user experience。


With the development of computer display technology, liquid crystal displays have gradually replaced CRT displays, and the importance of screen saver programs has gradually decreased. But in certain special occasions, such as industries that require long-term operation such as finance and security, screen saver programs still have certain application value。


Can the screensave file be deleted?

A screen saver file is a part of a computer system that is typically stored in the system folder of the operating system. If you do not want to use a screen saver, you can disable it by changing system settings, but it is not recommended to delete the file directly.

Deleting screen saver files may cause some issues, such as:


The screen saver file may be associated with other system files, and deleting it may cause system errors or crashes。


If you want to re-enable the screen saver in the future, you will need to reinstall or restore the file, which may require time and effort。


Removing the screen saver file may compromise the security and stability of the computer, as it may contain system level code and configuration information。


It is not recommended to delete screen saver files unless familiar with them. If you want to disable a screen saver, you can make changes in system settings or choose another screen saver to replace it。
