After completion the found images' thumbnails will display in the thumbnail view and be available under the folder tree's Found Files group, in the Similar Images icon.


NOTE: When sorting by similarity, ThumbsPlus shows the decoration on images whose color and shape metrics match the prior image exactly. This DOES NOT mean that the related files are identical! In order to see if two or more image files are byte-per-byte identical you must compare their MD5 digests. If they match, this is almost guaranteed to mean the files are duplicated, as long as the thumbnails are up-to-date. The easiest way to find out if the MD5 digests of similar images match is sorting the thumbnail view list by MD5; if the thumbnails are listed side-by-side and the second has a decoration, then their MD5 digests match and the files are identical.
