Accidentally Deleted Important Files: What To Do First

Stop using the drive

• Don't install recovery software onto the drive you need to recover from. The installer itself writes data.
• Don't save, download or copy anything new to that drive.
• Don't defragment it, don't run optimisation tools and don't let a cleaner utility loose on it.
• Don't format it, even if something suggests you should.

Check the places the file might still be, in order

1. 1

   The Recycle Bin

   Obvious, but it catches most cases. Open it, find the file, right-click and choose Restore. Files deleted from a USB stick or a network location don't go here, and neither do very large files or anything removed with Shift+Delete.

2. 2

   Search for the filename

   Files get moved rather than deleted more often than people expect. Search the whole machine for the name, or part of it, before assuming the worst.

3. 3

   Your cloud storage's own trash

   OneDrive, Google Drive, Dropbox and iCloud all keep deleted items for a period, in a recycle bin on their website that is separate from the Windows one. This is the single most common successful recovery route and people forget it constantly.

4. 4

   Version history

   If the file was in a synced folder, or edited in Office or Google Docs, there is often a version history you can roll back to — useful when the file still exists but has been overwritten with something wrong.

5. 5

   Previous Versions in Windows

   Right-click the folder that contained the file, choose Properties, then the Previous Versions tab. It only has content if File History or restore points were configured, but it costs nothing to look.

6. 6

   Any backup you have

   An external backup drive, a work backup system, or an older copy on a USB stick. An older version of a file beats no version at all.

7. 7

   Check email and messaging

   Documents and photos are often sent to someone at some point. Search your sent items for the filename.

About recovery software

File recovery tools can work well, and they can also make things worse when used carelessly. Two rules matter more than which tool you pick.

• Install the tool on a different drive from the one you are recovering — ideally run it from a USB stick, or connect the affected drive to another computer.
• Recover to a different drive too. Writing recovered files back onto the same disk can overwrite the very data you haven't recovered yet.

Why SSDs are different

On a mechanical hard drive, deleted data typically stays physically on the platters until something overwrites it, which is why recovery can succeed weeks later. Solid-state drives work differently. Most modern SSDs use TRIM: when you delete a file, the operating system tells the drive those blocks are no longer needed, and the drive clears them in its own time as part of housekeeping. That happens in the background, often within minutes.

The practical consequence is that recovery from an SSD after a deletion is far less predictable, and acting quickly matters much more. It is not automatically hopeless — timing, drive behaviour and whether the machine has been used since all play a part — but nobody can promise the data is still there.

This is not the same as a failing drive

Accidental deletion is a logical problem: the hardware is fine and the data may still be present. A failing drive is a physical problem, with different symptoms — clicking, disappearing from the system, read errors, extreme slowness — and a different approach, because continuing to power a failing drive can make things worse. If your files disappeared on their own rather than because someone deleted them, read our guide on recovering files from a failing hard drive instead.

When to bring it in

If the files genuinely matter — business records, the only copies of photos, coursework — bringing the machine in before attempting anything yourself is the safest route. We work from an image of the drive wherever possible, so recovery attempts don't put the original at further risk.
