XnView, simply put, is a file explorer. What makes it a bit special is that instead of treating every file as equal, it tries to make sense of each and every one and let you see, in the most relevant form possible, what exactly is contained in the file.

When checking this program out, we were immediately reminded of another quality file previewer, ACDSee. While that has gone on to become a fully featured photo manager, available for $50, XnView will take care of most users’ basic needs while boasting a price tag of $0 (for personal use). With its built-in preview engine, the program can display 400 different image file formats as well as play various media formats such as AVI or MP3.

Using the program will already be second nature to most users as it works like Windows Explorer. On the left side of the screen you see all your directories, with the contents of the directories being displayed in the upper half of the right window. Selecting any of these files will then bring up a preview in the lower half of the window. If you’re browsing through some photos you can run them as a slideshow and view in full screen. If you’re browsing through simple TXT or INI files, the opening few lines of text will show up as an icon and you can view the entire contents of the file without needing to open other programs.

There is a good level of support for various formats and the interface zips along without delays, even when displaying large video files. On encountering a file that it doesn’t recognize, XnView displays its hash values, which may or may not be of use. If you run into any difficulty, there is a help file that is sufficient but not overwhelming.

One aspect that wasn’t quite as we would have liked was that it didn’t recognize the native format of files. For example, a simple text file with a LOG extension wasn’t treated as the same file with a TXT extension. It’s a small inconvenience but does stand out because of the general high quality of the software. For anyone with a large number of files that they want to organize, convert or just browse, XnView is certainly worth a look.
