Portable Awesome Duplicate Photo Finder

This is the portable counterpart of Awesome Duplicate Photo Finder, a user-friendly and fast tool that identifies duplicate pictures in any selected directories, letting users remove them to free up space.
Since installation is not a requirement, you can drop the executable file in a custom location on the hard disk and just click it to run.
There is also the possibility of saving Awesome Duplicate Photo Finder to a USB flash disk or similar storage unit, to be able to run it on any PC with minimum effort and no prior installers.
An important aspect to take into account is that the Windows registry does not get updated with new keys, and no additional files are created on the HDD, leaving it clean after removing the program.
The interface is represented by a normal window with a pretty straightforward look. Using the folder view or drag-and-drop support you can point out directories or entire drives, include subdirectories as well, and start the scanning procedure with the click of a button.
Awesome Duplicate Photo Finder looks for BMP, JPG, GIF, PNG and TIFF files; any of these formats can be excluded from the search. Results show the full path for each original image and its selected duplicate, along with the similarity ratio. You can preview them in the main panel.
In addition, you can set Awesome Duplicate Photo Finder to send files to the recycle bin instead of deleting them permanently, perform this action without confirmation, look only for pictures with 100% similarity match, as well as to automatically check for updates online.
The app may take a while to carry out a scan job but it's pretty fast. It has a good response time and uses low CPU and RAM, so it does not affect the overall performance of the PC. We have not come across any kind of issues throughout our tests, since the app did not hang, crash or display errors. All in all, Awesome Duplicate Photo Finder serves its purpose.
