First of all, you need to know that RAM has a maximum read/write speed of 100 times that of SSD and 200 times that of HDD. Therefore, when the physical memory is large enough, we can use some tools to create a virtual disk partition in the memory to specially store some frequently used programs and files (mainly temporary files generated by operating system or web browser), thus significantly improving the running speed of OS and software, and extending the service life of HDD and SSD.

VLC media player (VLC for short = abbreviation of VideoLAN Client) is a free, open-source and cross-platform multimedia player developed by VideoLAN from France.

However, because most of the VLS functionalities had been integrated into VLC, they eventually renamed this project VLC media player.

The advantages of simplifying system installation files are obvious: 1) greatly shortens the installation time of OS; 2) saves a lot of disk space occupied by system partition; 3) makes the system run faster; 4) there is no need to manually remove unwanted/unused files one by one after installing the system (otherwise, that's not only extremely inefficient, but also error-prone, and the these files can not be removed completely. So it's better not to install them at all). Besides, integrating drivers, patches, software and other resources into the system installation package can greatly reduce the time and effort spent on driver update, patch update, software installation and other aspects for a newly installed system.
