"Cloud" is a free green software that can create a green virtualization environment for software operation on the user's computer, thereby achieving risk-free virtualized software operation.
The principle of this software is to first establish a hidden cache area on the user's disk, which is used to store various software downloaded by the user. Then, when the software is installed and running, "Cloud" will use the cache area files to project onto the disk and registry, in order to achieve the purpose of creating a virtual software operating environment. In this way, all user operations on the software are completed within the virtual environment, without affecting the registry, disk, or file IO, thus maintaining the system's cleanliness and greenness over a long period to the maximum extent.
More importantly: Software downloaded and used via "Cloud" can be immediately restored after a system reinstallation simply by reinstalling Cloud—no need for re-downloading. You can even place Cloud and its software cache on a USB drive, allowing you to plug it into any computer and launch Cloud to instantly use all your software, making it extremely convenient.
