The information pane

In the lower left corner of the window, you’ll find the information pane, which will display detailed information about whatever object you have selected in the rest of the window. You can use this to see information for a library, album, moment, or individual photo. The following information is displayed here:

Libraries: the library’s name, version, size, and location on your computer.

The size shown is for the entire library package, including all of Photos’ own data files. Note that this size will be larger than the size shown in Photos itself, which only adds up the space taken up by the photos themselves.

If you see “From unsupported macOS version” in the Version field, that means that the library is from a version of macOS not yet supported by the copy of PowerPhotos you have installed. The most common instances would be a very recently release patch or a public beta build of an upcoming macOS version. If you are running a non-beta macOS, select the “Check For Updates” menu item to download the latest version of PowerPhotos.

Albums: the album’s name and description, and the number and size of the photos it contains.

Moments: the moment’s name, date, and description, and the number and size of the photos it contains.

Photos: all of the photo’s attributes (name, date, favorite, keywords, description, faces, place, kind, and size) as well as the full paths to both the original and edited versions of the image.
