free software for Windows

Everything

Get Everything (and faster). Everything is a super-fast desktop file-search that integrates in your right click context menu. What makes Everything better is that it is able to bypass Windows on your desktop or laptop when searching which makes it faster to find your files because it does not scan the hard drive. Everything uses the raw Master File Table for NTFS drives, which logs all changes made on the partition and gets straight to the files you want faster and with stability.

Dusty

If you ever wondered how smoke behaves during any particular scenario, then you could definitely benefit from having Dusty in your computer. Now, I know you're probably scratching your head and asking yourself, "what do I need a smoke simulator for?" Well, for one, it's helpful if you're an animator, game developer or artist and you want to realistically portray how smoke would flow when a fire is lit up. The program is available for download on Windows but there's also a Mac version. The algorithm is based on the Stable Fluids Algorithm created by Jos Stam. If you're interested, you can hit the download link above the image to get this cool software.

WinDirStat

Freeing disk space is always a great way to speed up your PCs functions, but how do you figure out which program/file is hogging all your memory space? If you have been looking for an effective software to help you with this, WinDirStat is your best solution. WinDirStat is based on the Linux application KDirStat. Both programs offer you a visual display of your memory space and hard drive. It allows you to identify which programs take up too much space, consequently slowing down your PC. It also provides a clean up option if you want to fix the problem right away.
