Guide - Is there a way to delete individual files from My Passport backup disk

Western Digital’s My Passport external hard drives are popular for backing up personal data and storing large files securely. But one common question users ask is:
"Can I delete individual files from my My Passport backup disk?"

The short answer: Yes — but it depends on how the backup was created.
This article explains when and how you can delete individual files, what to watch out for, and how to manage your My Passport backup disk effectively.

 First, Understand How Your Backup Was Created

Before you delete anything, it’s important to know how your files were backed up:

1. Manual File Backup (Drag and Drop)

If you manually copied or dragged files/folders to the My Passport drive:

  • The files are treated like regular files on any external storage.

  • You can delete, move, or edit them individually.

2. WD Backup Software (Automated Backup)

If you used WD Backup or WD SmartWare:

  • Files are often stored in a structured folder system (e.g., with timestamps).

  • Deleting individual files is possible, but it can be risky if you’re unfamiliar with the file structure.

  • Files might be duplicated in backup sets, so deleting one version doesn’t always free up much space.

 

How to Delete Individual Files (Manual Backups)

If your backup was done manually:

  1. Connect your My Passport drive to your computer using USB.

  2. Open File Explorer (Windows) or Finder (Mac).

  3. Navigate to the folder where the file is stored.

  4. Right-click the file you want to delete and choose Delete (Windows) or Move to Trash (Mac).

  5. Empty the Recycle Bin/Trash to permanently remove it.

✅ This method is safe if you know exactly which files you no longer need.

 How to Handle Deletion from Software-Based Backups

If you used WD Backup or another backup utility:

  • Files are often stored in folders labeled by computer name or backup date.

  • To delete individual files:

    1. Navigate to the backup folder.

    2. Open folders carefully and identify file names or extensions.

    3. Delete only the file(s) you recognize.

    4. Avoid deleting system or metadata folders, as this can corrupt your entire backup.

 Be cautious: deleting the wrong file might affect backup integrity.

 

What About File Versioning?

Backup software like WD Backup may save multiple versions of a file over time. If you're trying to save space:

  • You may need to manually delete older versions of large files.

  • Some software allows you to adjust version retention settings, so only the latest copy is stored going forward.

Check your WD Backup settings for options like:

  • “Keep last version only”

  • “Keep versions for X days”

 Alternative: Clean Up Entire Backup and Start Fresh

If your backup drive is full or cluttered, and you’re unsure which files are safe to delete:

  1. Copy any important data off the drive.

  2. Format the drive (this erases all content).

    • On Windows: Right-click the drive in File Explorer > Format.

    • On Mac: Use Disk Utility > Erase.

  3. Re-run your backup with only the data you want.

✅ This is the cleanest option when dealing with an overloaded or outdated backup set.

 

 Final Tips: Managing My Passport Backups Safely

  • Always double-check files before deleting — especially backups.

  • Use manual backups if you want full control over file storage and removal.

  • If using WD Backup, regularly review the backup schedule and retention settings.

  • Consider using third-party backup software like Acronis, Macrium Reflect, or Time Machine (for Mac) if you want more granular control.

Deleting individual files from your My Passport backup drive is possible and safe — if you understand how your files were saved. Whether you're freeing up space or decluttering old backups, following the right steps ensures your important data stays protected.
