A Fast and Safe Way to Delete Duplicate Files on Mac, iPhone, and iPad

After scanning your Mac or iPhone and finding hundreds (or thousands) of duplicate files cluttering your system, manually selecting them one-by-one can waste 20-30 minutes or more. This is especially common when cleaning up duplicate files from cloud storage like iCloud or Dropbox. Auto Select solves this by automatically marking all duplicates for deletion in seconds while keeping one safe copy of each file. For typical scans with 1,000+ duplicates, Auto Select saves you 15-30 minutes compared to manual selection. The feature works identically on Mac, iPhone, and iPad.

What Auto Select Does

Auto Select keeps one copy per duplicate group and marks the rest for deletion. For a typical scan with 1,000 duplicate files, Auto Select completes the selection in a few seconds compared to 20-30 minutes of manual clicking. You control which copy to keep with two simple modes:

• Keep Oldest: Preserves the earliest created file in each group
• Keep Newest: Preserves the most recently created file in each group

The key safety feature: Auto Select only marks files for deletion, nothing gets deleted until you review and confirm. You stay in complete control.

How to Use Auto Select

Using Auto Select takes just a few clicks:

1. Scan for Duplicates

   Click "Find Duplicates" to scan your selected folders. Once the scan completes, you'll see all duplicate groups organized by content.

2. Click Auto Select

   Click the "Auto Select" button in the toolbar (shown in purple in the interface).

3. Choose Your Mode

   Select either "Keep Oldest" or "Keep Newest" based on which files you want to preserve.

   

4. Wait for Processing

   Auto Select processes all duplicate groups automatically. You'll see a progress indicator showing how many groups have been processed.

   

5. Review and Delete

   Files marked for deletion appear highlighted in red. Review the selections to ensure they match your expectations, then click "Delete Selection" when ready.

   

Keep Oldest vs Keep Newest: Which to Choose?

Choose Keep Oldest when:

• Working with archives or backups where the original file matters
• Dealing with photos where creation date indicates when the photo was taken
• Managing historical documents where the first version is important

Choose Keep Newest when:

• Working with edited documents where recent changes matter
• Managing downloads where newer versions fix bugs or add features
• Dealing with files that get updated over time

If unsure, Keep Oldest is typically the safer choice for photos and personal documents, while Keep Newest works better for software, downloads, and work documents. Want to learn more about why Zero Duplicates stands out from other duplicate finders?
