How to modify the location of my document in Win7 system

“My Documents” is a system folder in Windows. The system creates folders for each user. It is mainly used to save documents, graphics, and of course, to save any files of its users. How does the Win7 system modify my document save location?
My files in Windows7, my images, my videos, and my music are all saved in the C drive by default, and the files are stored for a long time. It will be more and more, taking up a lot of C disk space, making the computer slower and slower. Therefore, we need to change the default save location of my documents, my images and other folders to other partitions of the hard disk. C:UsersAdministrators
Open“My Computer”, enter the “C:Users your username” folder, or click on your login name in the upper right corner of the Start menu to open the Personal Folder.
By default, my documents, my images, my videos, my music, and downloads are all saved in this directory.
Right-click on my document, open the "Properties" dialog box, switch to the "Location" tab, enter the folder address you want to save, for example D:My Document, then click OK to save your changes.
If the newly set folder has not been created yet, the system will pop up a dialog box prompting us to select “ is ”.
Finally, the system will also prompt us to "move all files from the original location to the new location", and still select "ld"; is ".
After waiting for the system to move all the files in my document to the new directory, I have finished modifying the location where my documents are saved. Similarly, my images, my videos, my music, and downloads of several folders can be used to modify the save location.
