How to get more free space in your C:\?

 I have an SSD as my System drive and it always gets full even with all my Softwares and Data been saved in another HD.

Searching on the web, I found this article that really helped me.

The Complete Guide to Creating Symbolic Links (aka Symlinks) on Windows

Basically, you must:

• Copy the content of folder C:\Tmp into another partition, ex: D:\Tmp
• Right-click D:\Tmp and select "Pick Link Source"
• Go back to C:\, right-click and select Drop as "Junction"

C:\Tmp will be a "shortcut" to D:\Tmp.

The content will be at D:\Tmp, but if you write in the Console window C:\Tmp, you will see all the files.
