There is an option to detect duplicates, based on fingerprints. Those 
fingerprints have to be generated first, which can be quite long. 

To rebuild the fingerprint database, in the menu, go to 
"Tools"→"Maintenance"→"Rebuild Fingerprints", t

To actually find  duplicates, there are two options:
 - use the menu item "Tools" →"Find Duplicates".
 - use the "Similarity" tab in the left sidebar 

Disclaimer: never having used this tool, I don't know how fast or precise it 
is, backups recommended before deletions happen...
