Ultra File Opener can help you visualize the contents of a long list of file formats. The application has a user-friendly interface which adapts itself to the type of contents you’re viewing.
The tool lets you manage file associations and decide which extensions to open. I wouldn’t say it can open almost any file but it does support viewing an impressive number of 379 formats, and this figure continues to increase. Thus, the program can open practically every picture format, even RAW. Moreover, images can be converted into a different extension. Archives are also among the supported files and you cannot only view their contents but extract them as well. Likewise, audio and video files can be played but only if you download the required extension.
When the program is unable to let you view the contents of a file, it shows its code instead. Also, when an unknown extension is found, the program allows you to send the problem file to the support team. I was really pleased to find out that the program can open executable files and let you explore their contents. Moreover, you can even export some of those contents, such as images, icons and tables.
In general, this application works as a universal file opener, which may help you avoid installing a lot of viewing applications. Unfortunately, there are some very common formats that the program cannot render, such is the case of web pages.
