File Duplicate Manager - PROJECT IN PROGRESS and not working yet

This app resolves the problem I have with pictures automatically synchronising from my phone to my OneDrive folder. At the same time, I have some of these pictures already sorted and saved in various folders in the same OneDrive.

I needed a file manager able to find duplicates between two selected folders (including subfolders) and provide the functionality of selecting a location from which duplicates could be deleted with a single click.

Also, the program can extract the latest date from picture EXIF metadata, compare it with dates provided by Windows and display the oldest.

The app is written in Python which communicates with GUI through QT Widgets from the PyQt5 module. The GUI layout was created in QT Designer.
