What to do if…
you accidentally permanently delete an important folder and realise you need it today
Short answer
Stop writing new data to the drive the folder was on. Then immediately check service recycle bins, version history, and backups/snapshots—the “undo” paths are usually fastest.
Do not do these things
- Don’t install recovery tools onto the same drive you’re trying to recover from.
- Don’t keep saving new files to that drive “just for now” (use a different drive or cloud location).
- Don’t run disk cleanup/optimizer tools or “wipe free space.”
- Don’t repeatedly restart and retry random fixes—each change can reduce recoverability.
- Don’t assume “permanently deleted” means “gone” until you’ve checked cloud trash/recycle bins and version history.
What to do now
-
Freeze writes to the affected drive (30 seconds).
Stop downloads, updates, and heavy app usage. Pause syncing (OneDrive/Google Drive/iCloud/Dropbox) so the deletion doesn’t propagate or get “confirmed” everywhere. -
Identify where the folder lived (1 minute).
Local disk, external USB drive, network share/NAS, cloud-synced folder, or a SharePoint/Teams library. This determines the correct restore path. -
Check the fastest restore points first.
- Windows: Recycle Bin.
- Mac: Trash.
- Cloud: OneDrive Recycle bin; Google Drive Trash; iCloud Drive “Recently Deleted”.
-
If it’s cloud, use the web restore features (often the quickest “today” fix).
- OneDrive: Restore from the OneDrive Recycle bin first. If many files were affected, Restore your OneDrive can roll your OneDrive back to an earlier point in time (this feature is for Microsoft 365 subscribers and may depend on your work/school account settings).
- SharePoint/Teams files: Check the site Recycle Bin; if removed there, items may still be in the site collection (“second-stage”) Recycle Bin—a site owner/site collection admin may need to restore it.
- Google Workspace: Restore from Drive Trash. If Trash was emptied, a Workspace admin can recover deleted Drive items for up to 25 days after the Trash is emptied.
-
Use version history / backups / snapshots (especially if bins are empty).
- Windows: Go to the parent folder → right-click → Restore previous versions (works when File History/backups exist).
- Mac: If Time Machine was configured, use it to restore the folder from an earlier time.
- Network shares: Ask IT for a snapshot restore (many organizations keep hourly/daily snapshots).
-
If this is a work or school device/account: escalate now with the exact details.
Contact your IT/help desk and provide:- folder path and approximate deletion time,
- device name,
- whether it was OneDrive/SharePoint/Teams/network drive,
- whether you already paused sync.
Ask specifically for: Recycle Bin restore, version history restore, snapshot restore, or backup restore.
-
Create a “today workaround” without touching the affected drive.
- Ask a coworker to re-share or export the folder.
- Check email attachments, Slack/Teams uploads, project tools, or shared drives for copies.
- Look for ZIP exports, build artifacts, or earlier deliverables you can copy to a safe location.
-
If nothing works and the folder is truly critical: stop and preserve.
At this point, the safest move is usually professional recovery support or a careful approach that avoids writing to the drive (often by working from a clone/image). Avoid experimenting if the data value is high. -
USA-specific: if regulated data may be involved, notify the right internal owner early.
If the folder contained sensitive customer/patient/student data or other regulated information, notify your organization’s security/privacy contact so they can assess obligations (don’t try to self-diagnose compliance requirements—just flag the risk promptly).
What can wait
- You don’t need to decide on new backup software or a long-term storage plan today.
- You don’t need to pay for tools or run deep scans until recycle bins, version history, and IT/admin restores have been checked.
- You don’t need to “clean up” the drive—avoid changes until recovery is resolved.
Important reassurance
Accidental permanent deletion is common—especially with sync and shared libraries. The best “first aid” is to stop overwriting data and use built-in restore mechanisms quickly.
Scope note
This is first steps only, focused on maximizing recovery chances today. If recovery is complex or high-stakes, specialist IT or professional data recovery may be appropriate after these steps.
Important note
This is general information, not professional IT, legal, or forensic advice. Recovery options and retention windows vary by device, configuration, and your organization’s settings.
