How to Fix iCloud Error 4040

iCloud error 4040 indicates that a file or folder expected by your device could not be found in iCloud. You’ll see “The requested file could not be found (Error 4040).”

Step 1: What Causes iCloud Error 4040

• File deleted on another device and the deletion synced across all devices
• File removed via iCloud.com using the web interface
• Shared folder access revoked by the owner
• App uninstalled that stored data in iCloud, triggering automatic cleanup
• iCloud Drive sync glitch causing a stale file reference
• Account storage expired — Apple may remove data if iCloud+ payment lapses

Step 2: Check Recently Deleted Files on iCloud

iCloud retains deleted files for 30 days.

On macOS: Check Trash — files deleted from iCloud Drive go there. Right-click > Put Back.

On iPhone/iPad: Open Files > Browse > Recently Deleted and tap Recover.

On Windows: Check the Recycle Bin for the missing file and right-click > Restore.

Step 3: Recover Files from iCloud.com

1. Open https://www.icloud.com and sign in
2. Go to iCloud Drive > Recently Deleted
3. Select the file(s) and click Recover

For other iCloud data, go to Account Settings > Advanced where you can recover:

• Contacts — restore a previous contact list snapshot
• Calendars — restore calendar and reminder data
• Bookmarks — restore Safari bookmarks

Files deleted more than 30 days ago are permanently removed from iCloud.

Step 4: Restore Files from Local Backups

Using Time Machine (macOS):

1. Open the folder where the file was originally stored
2. Click Time Machine in the menu bar > Browse Time Machine Backups
3. Navigate to a date before deletion and click Restore

# List available Time Machine snapshots
tmutil listlocalsnapshots /

Using File History (Windows): Right-click inside the folder > Restore previous versions > choose a version and click Restore.

Check offline device copies: If a device was powered off when the deletion synced, it may still have a local copy. Turn it on without Wi-Fi, copy the file to USB, then reconnect.

Step 5: Prevent Accidental File Deletion

• Enable Time Machine (macOS) with an external drive for automatic backups of iCloud Drive files
• Set up a local sync mirror:

# Add to crontab (crontab -e) for nightly backup
0 2 * * * rsync -av ~/Library/Mobile\ Documents/com~apple~CloudDocs/ ~/Backups/iCloudMirror/

• Think before deleting — deletions sync across all devices instantly
• Keep iCloud+ active — if your subscription lapses, data may be removed after a grace period
• Check Recently Deleted regularly — files are only recoverable for 30 days
