There are so many file types available that keeping track of all of them is something that even the most experienced computer users can't do. Sooner or later you may also encounter file formats that you've never met before and that your system can't open, because no installed application is associated with that file type. File Type Advisor comes to help with this kind of files.
File Type Advisor is a very simple and straightforward program that shows relevant information about unknown file formats, helping you find out how you can open those files. It's very easy to use: it only comes with a single window where you input the file format, then a webpage is opened by your default browser and presenting various data about the requested file format. Since it uses a very large database of file extensions with related information, File Type Advisor is also reliable and accurate.
File Type Advisor can also help you keep your applications up-to-date by notifying you when newer versions of the installed programs are released. Last but not least, this handy tool is also completely free.
In conclusion, File Type Advisor is a nice tool to have if you have to deal with unknown file formats often, but I really wonder why directly searching for information about a specific file format on the Internet (using your web browser) is not a solution just as good as the one offered by this tool.
