Over the last years computer processors have become very powerful, so powerful that most of the time they do nothing but waiting your hard drive to throw some data at them. Fortunately, disks have evolved, too and a new generation of super fast disks called Solid State Drives (SSDs) has appeared. With an SSD your computer will become noticeably faster and reliable and will consume less power. The problem is that SSDs are too expensive, so you will have to get one which is considerably smaller than a regular mechanical hard drive. Smaller drive means that rather sooner than later you will face the "not enough free space" problem. In this article I'm going to show you how to free up gigabytes of disk space on an SSD in Windows 7, but most of the tips also work for Windows 8 and Windows 10.
