Ultra File Opener review
A Windows file viewer with broad format support and useful conversion tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Ultra File Opener is a Windows desktop application for opening and viewing a broad range of files. It supports images, text documents, source code, configuration files, HTML, XML, archives, audio, video, ebooks, CAD files, camera RAW files, and partially downloaded files. It is suited to Windows users who want one desktop tool for viewing diverse formats, with added conversion, printing, archive extraction, batch image conversion, and basic text editing.
Its main strength is breadth. The application can view over 500 file types and work with compressed archives, office-style documents, code, configuration files, and RAW camera files. It can also convert files to other supported formats, print with multiple templates, batch-convert images, and inspect or resume partially downloaded files. That combination makes it more useful than a viewer limited to previews, particularly for users who regularly encounter varied file formats.
Ultra File Opener follows a freemium model. The vendor offers a free Windows Store version with limited viewing, while the paid version adds capabilities such as opening, converting, and printing file types. The Single PC License includes free product updates and technical support for one year, and the Family Pack Upgrade extends the license for up to three PCs. Choose it if you want broad file coverage and desktop conversion tools on Windows. Users seeking a macOS or mobile application, or only a basic free viewer, should consider a narrower alternative.
