Delete Dropbox PNG files older than 48 hours on a schedule

🚀 What this workflow does

This workflow automatically scans your Dropbox for .png files and deletes any that are older than 48 hours, helping you keep your storage clean and organized without manual effort.

It’s ideal for workflows that generate temporary files such as AI images, exports, or cached assets.

⚙️ How it works

1. Schedule Trigger
   Runs every 2 days to perform automated cleanup

2. Search Dropbox Files
   Retrieves all .png files from your Dropbox account

3. Filter Files (Code Node)
   Keeps only files that:

   • Are older than 48 hours
   • Match the .png format
   • Are not in excluded paths
   • Are not protected filenames

4. Loop Over Items
   Processes files in batches to avoid API rate limits

5. Delete Files
   Permanently removes the filtered files from Dropbox

🧩 Requirements

• n8n (cloud or self-hosted)
• Dropbox account
• Configured Dropbox OAuth2 credentials

🔧 Setup

1. Import the workflow into n8n
2. Connect your Dropbox OAuth2 credentials
3. (Optional) Adjust the schedule trigger
4. Test the workflow with sample files
5. Activate the workflow

🎛 Customization

• Change file age limit
  Update the 48 hours logic inside the Code node

• Target different file types
  Replace .png with .jpg, .mp4, etc.

• Exclude additional files/folders
  Add paths or filenames to the exclusion list

• Adjust execution frequency
  Run daily, hourly, or based on your workflow volume

⚠️ Important notes

• Files are permanently deleted (no recovery step included)
• Always test before enabling in production
• Ensure correct permissions in your Dropbox credentials

💡 Use cases

• Clean up AI-generated images automatically
• Manage temporary automation files
• Prevent Dropbox storage overflow
• Maintain clean file systems for pipelines

🏁 Summary

This workflow provides a simple and reliable way to automate file cleanup in Dropbox.
By combining scheduled execution with smart filtering, it helps you maintain an efficient and clutter-free storage system.
