There are a lot of good and free games, but after having been played, most of which may be generally deleted from our hard drive without hesitation, especially those that are easily up to several GBs or even more so-called masterpieces.

For a small team/studio of only few members, under the condition of urgent time, documents or something similar must be economized wherever possible. However, two of them can not be ignored absolutely, also we should try our best to do them well and keep them updated. The two documents are: one is database models made by Power Designer (or the more advanced domain model), the other one is the wireframe.

Since have one computer, I don't want to use my head. So many times when needs calculation, I like to use a calculator, such as calculating oil consumption, calculating salary income and so on.

ImageSorter is the world's first image viewer application which can classify images automatically. Its purpose is to help you find the images that you forget which folder you put but remember what they look like. If you choose multiple folders, the images inside these folders will be arranged in accordance with the visual relationship, i.e. similar pictures will arranged together. In this kind of display mode, looking for a designated image will become much more easier. The selected images can be copied, moved or deleted (in the right-click menu).
