Ultra File Opener is a universal file viewer that lets you open a large variety of files. No less than 350 different file types can be opened using this tool. It allows viewing images or even text files, but it also provides with handy additional features and functions such as the possibility to convert picture files or extract archives.

I like about this tool the fact that it can open even the files that it doesn’t support and display them in hexadecimal (hex) viewing mode. When it comes to images, you can also convert them to other formats or zoom and rotate them when viewing them. The popular formats like JPEG, PNG, TIF, GIF, BMP, are supported for viewing, as well as RAW formats from digital cameras. For archives, renowned formats like ZIP, GZ, TAR, 7Z, GZIP are supported for being extracted, even if they are password-protected.

A truly special feature is the support for files that were partially downloaded by your web browser. It can resume the download of such files when it was interrupted by whatever reasons. The .CRDownload, .Partial, and .Part extensions are supported.

As you can see, Ultra File Opener can be useful in a lot of ways and for a lot of purposes. It’s a nice tool that proves to be worth a try.
