A lot of useless PSD files are released daily simply because the authors think quantity is quality. It is obvious that such a mentality is incorrect and should be corrected. The PSD files that I selected for this article are rigorously selected and it took me a while to filter all the useless ones that are being passed around on the internet. I may have missed a few free premium-like PSD files, but that's only because I can't reach the whole internet for a research. However, from the sites I know that produce top quality PSD files I've selected these 39 interesting freebies that could help you on your projects. You'll notice pretty fast that they are all UI elements and not other types of PSD files that can't be put to a good use.
