Duplicate Cleaner Pro

Duplicate Cleaner is made by DigitalVolcano Software Ltd, a UK-registered company that has published Windows utilities since 2006. It deep-scans a drive or network share for redundant files of any type, then goes further than a simple checksum match: photos are compared even after cropping, rotation or resizing, music is matched by audio content or tags, and video is matched by frames, soundtrack or metadata, with a Selection Assistant to help pick which copies to keep.

Duplicate Cleaner Pro 5 is a perpetual licence — no subscription — priced in your local currency at checkout, with a 7-day free trial and a site-licence option for businesses running it across many machines at one location. DigitalVolcano's own privacy policy states plainly that the company is UK-registered, which puts it outside the EU and EEA under the United Kingdom's adequacy decision rather than direct GDPR membership.

None of the other tools in this category treat duplicate-finding as their main job; O&O, Ashampoo and Abelssoft fold something similar into one feature among many inside a broader cleanup suite. For a Windows user whose actual problem is thousands of duplicate photos or a music library copied twice during a laptop migration, that single focus is the whole appeal.

What Duplicate Cleaner Pro does well

• Matches photos, music and video by content, not just file name
• Perpetual licence, no subscription required
• Free 7-day trial
• Site licence available for multiple installs at one location
• UK-registered company, publishing software since 2006

Where Duplicate Cleaner Pro falls short

• United Kingdom, outside the EU and EEA
• Exact price only shown at checkout, not on the price page itself
• Windows only
• Narrower than a full cleanup suite: duplicates only

Standout feature. Matches near-identical photos and re-encoded videos, not just files with the same name and size.
