How to Recover Deleted or Lost Files on Mac
Successful recovery depends on what happened after the files were lost. Stop writing new data to the affected volume, check Trash and available backups first, then scan only if the files are still missing. Save recovered files to another healthy drive so the recovery process does not overwrite data you still need.
Quick answer
Stop using the affected volume, check Trash and Time Machine, connect a separate destination drive, scan the correct source with GiliSoft Mac Data Recovery, preview the results, and recover selected files to the separate drive.
Choose the Safest Recovery Path
| Situation | Start here | Important limit |
|---|---|---|
| Recently deleted file | Check Trash, iCloud, and Time Machine before scanning | Do not create or download files on the affected volume |
| Emptied Trash or deleted external-drive file | Scan the original source volume | Recover to a different healthy drive |
| Formatted or inaccessible volume still appears in macOS | Preserve it, then scan or make an image first | Do not erase or reformat it again |
| Disk is missing, clicking, disconnecting, or reported as failing | Stop and use qualified recovery service | Repeated scans may worsen physical damage |
| Encrypted volume is locked | Unlock it with the valid password or recovery key | Recovery software cannot bypass FileVault encryption |
Step-by-Step Workflow
- Stop writing to the affected volume
Quit apps that save to it, avoid installing software there, and do not download, export, or recover files back to the same volume.
- Check built-in recovery options first
Look in Trash, iCloud recently deleted areas where applicable, and Time Machine or other backups. Restoring from a verified backup is usually the safest path.
- Connect a separate recovery destination
Use a healthy external drive with enough free space for the files you expect to recover. This drive must not be the source being scanned.
- Select the correct source volume
Open GiliSoft Mac Data Recovery and choose the internal volume, external drive, memory card, or other accessible device where the files were lost.
- Scan and narrow the results
Let the scan finish, then filter by path or file type and preview representative files before selecting a large recovery set.
- Recover to the separate drive
Save selected results to the healthy destination, open several recovered files, and keep the source unchanged until the important data has been verified.
Important Limits and Safety Checks
Frequently Asked Questions
Can I recover files after emptying Trash?
Sometimes, if the underlying storage blocks have not been reused or cleared. Stop using the affected volume and scan it from a recovery environment that writes results elsewhere.
Should I run Disk Utility First Aid before scanning?
First Aid is for file-system structure problems, not undeleting files. If a volume is unstable or physically failing, preserve the data first. If the disk is healthy and the issue is directory damage, follow Apple guidance and work from a current backup when possible.
Why must recovered files go to another drive?
Writing them to the source can overwrite blocks that still contain other missing files and reduce the chance of a complete recovery.
Can FileVault-protected data be recovered without the password?
No. The volume must be unlocked with valid credentials or a recovery key before its decrypted file system can be meaningfully scanned.
What if the drive does not appear in Disk Utility?
Check the cable, enclosure, power, and another port. If the device remains missing, disconnects repeatedly, clicks, or is reported as failing, stop software scans and consult a qualified recovery service.
