    WinDirStat: Windows Directory Statistics

    WinDirStat: Windows Directory Statistics

    A disk usage statistics viewer and cleanup tool for Windows

    WinDirStat (Windows Directory Statistics) is a disk usage statistics viewer and cleanup tool for Windows. On start up, WinDirStat reads the whole directory tree once and then presents it in three useful views: - The directory list, which resembles the tree view of the Windows Explorer but is sorted by file/subtree size, - The treemap, which shows the whole contents of the directory tree straight away, - The extension list, which serves as a legend and shows statistics about the file types. Visit the WinDirStat blog for more up-to-date information about the program. Note: If you are looking for an alternative to WinDirStat for Linux, then you are looking for KDirStat (apt-get install kdirstat on Debian-derivatives), and the alternative to WinDirStat for MacOS X is Disk Inventory X or GrandPerspective.

    Cytadela

    Cytadela

    An old-school first person shooter from classic Amiga computers

    A conversion of an Amiga first person shooter from 1990's. Some say it's a Doom clone, but some argue that it's a Wolf 3D clone. The Citadel is a secret military research base located on a distant planet. After the contact with the base has been lost, a military spaceship has been sent there with a mission to either restore the communication or, if that's impossible, destroy the base. While approaching the planet, the spaceship has been destroyed by the Citadel's defence systems and you, as the only survivor, have no other option but to fulfil the mission on your own - you have to destroy the Citadel. In order to do that you have to penetrate the whole base, find six parts of a bomb and plant it in the Command Centre. Your task is by no means simple - there are hordes of enemies who will try to stop you, and you will have to solve many riddles in order to find your way through the base.
