MediaInfoXP is a minimalist version of MediaInfo, an Open Source app that can display all available information about your media files.
MediaInfoXP is portable and requires no installation. Just extract to a folder and run. You can drag-and-drop and music or videos directly into the application or open them under the Application tab.
It immediately displays a wealth of information, including name, format, date, bitrate, channels, sampling rate, and more in different categories, for example, General and Audio for music files. You can now save, copy to your clipboard, clear the list, open new, or exit.
MediaInfoXP has a short review and only two screenshots here, but that's a good thing because, after all, its goal is to be a minimalist application.
