The Windows Club is featuring a search utility for your Windows-based computer, called File Seek, which is faster (with more options) than the built-in Windows search options. If you go to the File Seek download page you will see a “full install version” and a version that you can download without the installer (portable app). I typically, with these types of utilities, will download the portable version to test them out; plus, the portable version will typically leave the registry alone.
File Seek Free version offers limited features, but they are still useful. The free version is excellent, keeping in mind the number of features it offers, and how fast it can find the files. You can download it from its homepage.
