Features
• Scan for duplicate files
Cloud Duplicate Finder's primary feature is to help users find and delete duplicate files in supported cloud drives. It supports finding all common types of duplicates, such as duplicate photos and documents.
It can scan specific folders but can't find duplicate files stored directly in your drive's root folder. In the test, it found 28 groups of duplicates, and its desktop counterpart found 81 groups (since many duplicates were located in the root folder).
• Scan for similar photos
Cloud Duplicate Finder also provides a Similar Photo Finder feature. Switching to this feature allows you to scan for similar photos in OneDrive and Google Drive. You can adjust the Scan Level to customize how strictly the feature considers photos as similar ones. In the test, it returned nothing, suggesting that the feature may not be very effective.
Price: Is Cloud Duplicate Finder free?
No.
Cloud Duplicate Finder allows you to find duplicate files for free, but you need to pay to delete duplicates. There are multiple subscription options.
| Subscription | Cost | Optionally bundled with |
|---|---|---|
| Quarterly | $39.97 | Easy Cloud Manager |
| 1 year | $69.97 | Easy Cloud Manager |
| 2 years | $96 | Easy Cloud Manager |
| Lifetime | $250 | Easy Cloud Manager |

Features
• Remove duplicate files
Cisdem Duplicate Finder can find all types of duplicate files (images, videos, documents, audio, and more). It throughly scans your drive or selected folders, including the root folder, without missing any duplicates.
It provides two methods for handling cloud drives:
- Method 1: Scan for and remove them directly online (for Dropbox and OneDrive only).
- Method 2: Sync files from cloud to your computer using your drive's official desktop app, then scan for and delete duplicates locally. (The drive's desktop app will automatically detect and sync any duplicate deletions.) This method supports all cloud drives with a sync feature.
Note
The first method is available on Windows PC only. If you are a Mac user, you can use the second method.
• Detect duplicate files
Its similar image detection can be turn on or off. If enabled, it can find similar photos based on your settings. For example, you can customize which image comparison technique(s) to use and adjust the similarity thresholds for image comparisons.
Price
It offers two purchase options: $19.99 for One-Year Subscription, and $39.99 for one-time purchase.
