Test ExactDupe

Press Load demo results on the main page. You should see two exact duplicate groups, three extra copies and non-zero potential space.

Real-file test

Create a temporary folder. Put a file called original.txt in it, copy that file twice under different names, and add one different text file. Run ExactDupe with the minimum size set to 0 B. The three copied files should appear in one exact duplicate group while the different file should not.

Cross-folder test

Copy the same test file into two different temporary folders. Add both folders to ExactDupe and scan. Matching names are not required: changing one copy's filename should not stop an exact match because the content hash is what matters.
