Another way
The same name and size usually means the same file, but a later download can be an updated version.
With Omaculate
Omaculate compares the actual content. Its Trash duplicate downloads recipe only lists a numbered copy when it is byte-for-byte the same as the original beside it, and the original is never touched.
