FAQs
Does it remove similar photos automatically?
By default, only exact duplicates are auto-marked. You can enable automatic selection for similar photos in Preferences → Similar Images and choose whether to keep higher-resolution, higher-quality, or follow the duplicate rules.
Can I exclude folders or file types?
Yes. Add exclusions by folder, file, or extension in Preferences. You can also ignore specific items from the results list.
Is it safe to use with Photos and Music/iTunes?
Yes. Cisdem integrates with Photos and Music/iTunes so removals go to their respective trash/recently deleted areas. You can review before permanently deleting.
What file types are supported?
Common image, video, audio, document, and archive formats are supported, plus duplicate folders. The app compares file content for accuracy.
