FreeFileViewer
Holbæk, Denmark
What it is
FreeFileViewer is a free Windows desktop application for viewing documents, spreadsheets, images, videos, and other files, plus playing audio. The listing specifies 217 supported formats, while the maker describes support for more than 200 file types. Unrecognized files can be opened as hexadecimal dumps for inspection and printing. The app can print most supported document, spreadsheet, and image files, and its installer includes the components it needs without requiring other software. Listed Windows versions are 10, 8, 7, Vista, and XP, in 32-bit and 64-bit editions. Installation makes FreeFileViewer the default viewer for supported file types without an existing default. Its personal-use license covers computers you own or control. Promotional information, advertisements, and third-party offers may appear during installation, inside the product, or on the website. Bitberry Software develops the app, which uses FFmpeg and related libraries for media playback.
