FreePanorama

If you're interested in photography, you might've encountered at least a couple of weird file extensions in various circumstances and were probably clueless on how to approach them.

As some of the formats can only be opened by specific apps, you might need a certain piece of software to handle them. For example, FreePanorama can help you view panorama PAN files on your PC with minimum efforts.

You don't need to install this application on your computer to benefit from its functions. Instead, you only have to launch its executable, as its controls are ready to use.

More so, the fact that it's portable means that it won't create additional files or folders on your computer, nor will it tamper with any of your Windows registry entries.

As its name frankly suggests, this application can help you view panorama files on your computer by enabling you with a bunch of useful controls. However, it can't process JPG, BMP or other formats, as it was only designed to handle PAN files.

As soon as you launch the app, you'll be prompted to provide it with a suitable file. Not doing so and canceling the dialog will also quit the application.

This app lets you enjoy a PAN file on your PC as simply as it can. That means that there are no complicated or hidden functions. You just open the file, drag to move around the image and use your mouse's scroll wheel to zoom in or out.

However, since it lacks a proper documentation file or section, new users might find it a tad confusing to operate controls that they don't know exist. But given that this app can only view PAN files, there's no way users can mess up their documents or various settings while attempting to enjoy a panoramic photo.

If you have a bunch of panorama PAN files on your PC and have no idea what to open them with, you might give FreePanorama a spin, as it can help you do so as quickly and effortlessly as possible.
