Accidentally Deleted Files? Do This Immediately.

Losing important files is one of those moments where your stomach drops and you immediately know you've done something you can't easily undo. It might have been an accidental Shift+Delete, an emptied Recycle Bin, a formatted drive or a laptop that just won't turn on. Whichever it was, what you do in the next five minutes matters more than anything else.

Stop using the device immediately. Every file you save and every app running in the background can overwrite the space where your deleted files still sit. The less the drive is used after deletion, the better the chances of recovery.

Why deleted files can often be recovered

When you delete a file, Windows doesn't immediately erase its contents. It marks the space as "available", but the actual data stays on the drive until something else is written over it. Think of it like removing a name from a library catalogue while leaving the book on the shelf. The book is still there until someone puts a different book in that spot.

This is why acting fast matters. On a drive that's actively being used, that space gets overwritten within minutes. On a drive you've powered off and put in a drawer, the data can survive for months.

What to do right now

01

Stop using the computer. Close everything. If it's a laptop, shut it down properly. Don't just close the lid. Every second of normal use risks overwriting your files.

02

Check the Recycle Bin first. If you didn't use Shift+Delete, there's a good chance your files are sitting in the Recycle Bin. Right-click → Restore. Done.

03

Check cloud sync. If you use OneDrive, Google Drive or Dropbox, log in through a browser on a different device and check the "Deleted files" or "Trash" section. Cloud services often keep deleted files for 30 days or more, even if they've left your Recycle Bin.

04

If none of the above — call us before trying recovery software yourself. DIY recovery tools can sometimes do more harm than good if used incorrectly. Bring the device in and we'll use professional tools to maximise recovery chances without risking further loss.

✓ It's usually fixable. In most cases where the drive hasn't been heavily used after deletion, Fentech can recover the files. We use professional-grade recovery tools and charge only if recovery is successful.

If the drive won't open or the laptop's dead

If the device won't turn on, or the drive shows errors, don't try to force it. Repeated failed attempts to spin up a failing hard drive can cause physical damage that makes recovery much harder. Power it off, leave it off, and bring it in. Logical failures (deletion, formatting, corruption) are usually recoverable. Physical failures are more complex but often still possible with the right tools.

The real lesson: backups

The only thing that takes the stress out of data loss is having a backup. Fentech can set up automatic cloud backup for your devices, so losing a file just means going back to yesterday's version instead of booking a recovery job. Get in touch if that's something worth setting up.
