Metadata++ is an ExifTool-powered tool for viewing and managing the metadata in pictures, videos, audio files and more.

The program looks and feels much like Explorer. Here's a folder tree on the left; there are the contents of the current folder in the centre; you can view this in thumbnail or details-type form.

At its simplest, this works as a capable metadata viewer.  Click an image and Metadata can display its basic information (format, resolution, encoding); file details (name, size, created/ modified/ last accessed dates); and a host of other Adobe, Exif, IPTC, XMP, GPS, ICC profile and other information.

Right-click the currently-selected files and you'll find options to remove, export or import metadata or save the data in one of multiple formats: HTML, HTMLDUMP, JSON, MIE sidecar, PHP, TXT and XML.

Metadata++ opens with one tab, but you can easily add more to browse and compare multiple folders at once.

While these functions worked more or less correctly, we also noticed lots of problems.

 - The drives under "This PC" are sorted alphabetically, so the sequence on our test PC went "Data (D:)", "OS_Install (C:)", and so on.

 - You can view thumbnails of images, but there's no double-click action to view them, not even in the default Windows viewer.

 - There's a Map function but it either didn't highlight geotagged files, or showed a map which didn't clearly indicate the location of the picture

 - Thumbnail creation can be very slow. We regularly thought the program had given up before finally they appeared.

 - There's a "double-click to edit metadata" function but this either didn't work for us, or we didn't understand it

 - We clicked a Help icon to test our understanding, and a browser window opened with an "error 404" message

 - The program crashed several times, and locked up once.
