How to Recover Deleted Files From a USB Flash Drive or SD Card

You deleted files from a USB stick or memory card, went to the Recycle Bin to get them back, and they aren’t there. That’s normal, and it doesn’t mean they’re gone. If you need to recover deleted files from a USB drive or SD card, your odds are often good, as long as you stop using the drive right now and follow the steps below in order.

Why deleted files from USB drives skip the Recycle Bin

On Windows, files deleted from removable drives such as USB flash drives and SD cards are usually deleted permanently. They don’t go to the Recycle Bin at all. Windows typically warns you with “Are you sure you want to permanently delete this file?”, but it’s easy to click through.

A few related cases:

• On a Mac, files deleted from an external drive go to a hidden Trash folder on that drive. Reconnect the drive, open the Trash in the Dock, and use Put Back.
• Cameras, phones and drones don’t have a trash folder. Deleting on the device removes the file immediately.
• Files in a synced folder (OneDrive, Dropbox, Google Drive) may also exist in that service’s online trash. Check there first.

The upside: “permanently deleted” usually just means the file system has marked that space as free. The data itself typically stays on the drive until something new is written over it.

Step 1: Stop using the drive immediately

This matters more than any software you’ll use.

1. Don’t save, copy or download anything to the drive.
2. If it’s a camera card, stop shooting and take it out of the camera.
3. Don’t format the drive, even if Windows or the camera asks you to.
4. Don’t run CHKDSK or “repair” tools on it. They can rewrite file system structures that recovery software relies on.
5. Eject it safely and set it aside until you’re ready to scan.

Flash drives and SD cards connected by USB generally don’t receive the TRIM commands that wipe deleted data on internal SSDs, so deleted files often survive for a while. But the drive’s own controller manages the flash memory in the background, so don’t leave it plugged in and in use for days.

Step 2: Check the easy places

Before reaching for software, rule out:

• The Recycle Bin, in case the files came from a computer folder rather than the drive.
• The original source. Were the files copied to the drive from a computer, phone or email? The originals may still be there.
• Cloud and backups. Anything synced to a cloud service or included in a backup can be restored from there.

Our general deleted file recovery guide covers these in more depth.

Step 3: Recover deleted files from the USB drive or SD card with software

If the files truly aren’t anywhere else, recovery software is the next step.

1. Install the software on your computer’s internal drive, never on the USB drive or SD card you’re recovering.
2. Connect the drive directly to the computer. For SD cards, use a reliable card reader.
3. Choose the drive in the software and start a scan. Most tools offer a quick scan for recently deleted files and a deep scan that searches for file signatures.
4. Preview the results. Photos and documents that open correctly in preview are usually intact.
5. Recover to a different drive, such as your computer’s internal drive. Never save recovered files back onto the drive you’re scanning.

Free options include PhotoRec (open source, works on Windows, Mac and Linux, and recovers many file types despite its name) and Recuva on Windows. Microsoft’s free Windows File Recovery tool also supports external drives; see how to recover deleted files on Windows for the basics. Before you choose a paid tool, read is data recovery software safe?

Recovered files often come back with generic names like f1234567.jpg and without their original folders. That’s normal when the file system records are gone but the data isn’t.

What if you formatted the drive?

Formatting is different from deleting, and the type of format matters:

• Quick format creates a fresh, empty file system but generally leaves the old data in place. Recovery software often finds most of it.
• Full format on Windows Vista and later writes zeros across the whole drive. Files are not recoverable after a completed full format, by software or by a lab.
• Formatting in a camera is usually a quick format, so the same recovery approach applies.

Read quick format vs full format to work out which one happened.

When it’s not deletion: the drive isn’t detected

Everything above assumes the drive still shows up and works normally. If it doesn’t, the problem is physical or electronic, and recovery software can’t help because it can’t reach the drive at all. Watch for:

• The drive isn’t recognized or doesn’t appear in File Explorer or Disk Management. See USB flash drive not recognized.
• Windows says “Please insert a disk into USB drive” or shows a capacity of 0 bytes. That usually points to a failed controller.
• An SD card won’t show up in any reader. See SD card not showing up.
• The connector is bent, loose or snapped, or the card is cracked.

Don’t keep plugging a failing drive in and out or forcing a damaged connector. Recovering these requires reading the memory directly, which is lab work.

The bottom line

To recover deleted files from a USB flash drive or SD card, stop using it immediately, check the original source and any cloud copies, then scan it with read-only recovery software installed on a different drive and save the results somewhere else. A quick format is usually recoverable; a completed full format is not.

If your flash drive or memory card has stopped being detected, is physically damaged, or software can’t read it, our USB and thumb drive recovery service (and SD card recovery for memory cards) can help. It’s one flat $1,200 price for a single device, with free prepaid shipping, and you pay nothing unless the recovery succeeds.
