Hello,
I have a problem with my SDD. The capacity should be 120 GB. Windows says I have around 14 FB of free space there. When I select all folders even the hidden ones, they add up to 40 GB, even WinDirStat says I have only around 40GB of files there, so there should be around 50 - 60 GB of free space but I only have 14GB. Anybody knows how to fix this problem?

You can see it all here: http://imgur.com/a/9MysE - some things are in Slovak language, I apologize for that but I am sure you can make sense out of it.
