Large hard disk is also used to modify the Win7 file storage location

        Many friends will list the size of the hard disk as the primary self-selection condition when buying a computer, but the hard disk will be larger, and the space used for a long time will gradually become smaller. When installing the software, the installation directory is changed to other partitions, but the C disk space is always occupied by the full, what files account for the C disk space? In the Win7 system, the temporary file is a large hard disk, and the most frequently read and written files in the system. Therefore, we recommend that you change the storage location of the temporary file to another partition to reduce the burden of the system disk partition. Avoid the space of the system disk is getting smaller and smaller, so that it constantly affects the speed of the computer.
Modifying the temporary file storage location does not require the help of third-party software, and can be modified by Win7's own settings. First open the Win7 control panel, enter "System and Security", open "Advanced System Settings" in the left navigation bar.

Advanced System Settings
Switch to the "Advanced" tab and open "Environment Variables".

Open Environment Variables
Select "TEMP" and "TMP" in the Environment Variables dialog box and click the "Edit" button.

Edit User Variables
In the Edit User Variables dialog box, we see that the variable value is the part that can be edited. Here we have the default temporary file storage address of the original system. We can directly use the user. And the system temp and tmp variables are changed to another path.
After changing the temporary file path, don't forget to delete the original temporary file directory completely. After deleting it, you will find that the capacity of the system disk partition is short, and it turns red to blue.
In addition, in addition to the large space, the read and write speed is very important. For example, the Samsung 900X series notebook is equipped with a faster SSD solid state drive, which greatly improves the data transmission performance and data security performance.
