If you are an administrator of a Windows computer, which has multiple user accounts and you feel the need to empty the recycle bin To free up some space on your hard drive, the first idea that comes to mind is probably to log in to other users' accounts and do the procedure manually.
However, there is a shortcut that you should know, it is a simple command line with which you can empty all users' recycle bins easily 
Of course, for the trick to work remember that your account must have the Administrator privileges.
Step 1:. Run command prompt
You can access it through the start button, typing CMD and right-clicking on it to choose the option "Run as administrator". Another quick way is to directly press the keys Windows + R y escribir cmd.
These are the 2 access options.
Step 2:. Type the command rd /sc:$Recycle.Bin
It is easy, once you are in the command prompt, with a right click you paste the following:
rd /sc:$Recycle.Bin
Press enter and it will ask you if you are sure you want to proceed with emptying the recycle bin, the letter S means yes and the letter N means no, as is more than obvious 
Something important to clarify is that this command only refers to the disk drive "C", so for your other drives you will have to change that letter to the corresponding one for your drive.
For example, if your main unit is the «D«: Changed by:
rd /sd:$Recycle.Bin
The command works perfectly in Windows 8 and 7, but for Windows XP, Vista or Server 2003 users, it changes to the following:
rd / sc: recycler
Another tip to take into account:
If you press the keys shift + delete at the same time, the file or folder you delete will not go through the recycle bin, but will be directly deleted. It is an old trick that some users know and many others do not, but it is good to comment on it.
