Compare images in directory or compare multiple directories using include subfolders toggle button. Comparison can be made by name, date modified, size, data, or all of the above to quickly identify images that are different. Further highlight images with a difference using built-in fast filter options for the display of all results, just matches, or non-matches. Images that don’t have a match will have a mark identifying them as a non-match. Ability to hide/show properties for date modified and size. Use the Include Subfolders option to list all images; including images nested inside other folders. Care should be taken using the subfolders option, as the processing time for comparison will be much longer for large lists.

Features:
- Compare images quickly.
- Images nested in subfolders can be compared.
- Multiple comparison methods; by name, date, size, and data.
- Preview images.
- Launch images in default app.

I am currently working on an app called Compare 2 Image. It will perform the same operations as its macOS cousin - Compare 2 Image for macOS.
I just finished the logic for image bytes comparison between two images. I also FINALLY got the async operations finished. The biggest hurdle was processing the image collection view using async Task logic, then waiting for its completion before running a comparison upon the 2 collections.
