1, and the paths are: c: \ program files \ NVIDIA corporation \ installer 2 and C:\NVIDIA.

2. The installation program of 2.NVIDIA is stored in these two directories. It can be deleted manually without affecting the function of the graphics card. The total size is about 2 g.

The second is the search service directory of Windows itself (it can be emptied around 500M).

1, the path is: c: \ programdata \ Microsoft \ search.

2. This directory stores windows index files, and the search service of WINDOWS is similar to google desktop, which exists for the convenience of users. But, on the whole, it is of little use. You can manually shut down the windows search service and delete the search directory.

Three. Office installation source files (about 1G space can be cleared)

1, the path is: C:\MSOCache.

2. This directory is the installation source directory of windows Offices. The main purpose is to add components to OFFICE in the future. If you don't modify OFFICE or don't have an installation disk in the future, you can empty the directory. You can clean up about 1G space for drive C. (Note: If it is not in the C drive directory, the MSOCache directory is the root directory of the partition where OFFICE is installed. )

Fourth, winsxs directory cleaning.

1, the path is: C:\\Windows\\winsxs.

2. This directory is complicated (don't clear all the contents of this folder directly), and most of the contents can't be deleted. However, temporary system update files and system update installation files stored in C:\\windows\\winxsx\\temp\\ and C: \ \ Windows \ Winxsx \ \ ManifestCache directories can be deleted. In addition, there are a large number of redundant update files in this directory.

3. If users are familiar with the WINDOWS 7 operating system, they can choose to use the mklink /j command launched by WIN7 to move the directory.

4, the use method is as follows:

MKLINK [[/D] | [/H] | [/J]] Link target

/D Create a directory symbolic link. The default is file symbolic link.

/H Create hard links instead of symbolic links.

/J Create a directory join.

Link specifies a new symbolic link name.

The target specifies the path (relative or absolute) referenced by the new link.
