Yes, you can usually get files back from a USB flash drive on a Mac. When you delete a file from a USB stick, the stick marks its space as free but doesn’t erase it. Unlike your Mac’s built-in SSD, USB sticks don’t use TRIM, so the data stays where it was until something new is written over it.
That makes the first step the important one: don’t save anything else to the stick. Then work through the steps below, starting with the ones that cost nothing.
1. Plug it in and check the Trash
When you drag a file from a USB stick to the Trash, it isn’t deleted yet. macOS keeps it in a hidden Trash folder on the stick itself, and it appears in the Trash in your Dock only while the stick is plugged in. So if you ejected the stick and the file seemed to vanish, plug it back in and open the Trash. Select the file and choose File ▸ Put Back, or drag it somewhere safe on your Mac.
If you emptied the Trash, or deleted the file on another computer or in a camera, it won’t be there. Move on.
2. Look for another copy
A USB stick is often the second home of a file, not the first. Check the computer you copied the files from, your email attachments, and Time Machine (it backs up your Mac rather than the stick, but it may have the folder the files came from). Search iCloud Drive and any shared folders too.
3. Stop using the stick
- Don’t copy new files onto it, and don’t install a recovery app onto it.
- Don’t format it, even if macOS or Windows says you need to. On a Mac, click Ignore when it says the disk is not readable.
- Don’t run Disk Utility’s First Aid on it yet. First Aid repairs a drive by writing to it. Get your files off first.
4. Scan the USB stick
If there’s no copy anywhere, a recovery app has to find the files on the stick. It reads every part of the stick, including the space marked as free, and rebuilds the files it finds. With Reco, which is free with no limit on files or size:
- Download Reco to your Mac.
- Plug in the stick and choose it in Reco’s list. It appears as soon as you plug it in.
- Run a deep scan. Reco reads the whole stick at the stick’s own speed. A small stick takes minutes. Cheap, slow sticks take longer, and Reco shows a time left that’s measured, not guessed. You can pause, or unplug and come back, and it continues where it stopped.
- Review. Photos and videos show as thumbnails. Each file shows how intact it is. Original names and folders come back where the stick still remembers them. Show each file once hides duplicate copies.
- Recover to your Mac or another drive. Reco won’t save onto the stick it’s reading, and it never writes to it.
macOS will ask for your password or Full Disk Access before Reco can read the whole stick. Reco says which one and uses it only to read.
USB sticks used with Windows PCs are usually exFAT, FAT32 or NTFS, and sticks used only on Macs may be APFS or Mac OS Extended. Reco reads all of them, so it doesn’t matter which computer the stick came from.
What usually comes back
| What happened | Chances |
|---|---|
| Files deleted, little saved since | Good |
| Stick formatted with a normal (quick) format | Good. See recovering a formatted drive. |
| Stick shows up but won’t open, or asks to be formatted | Usually good, if you don’t format it |
| Files deleted, then lots of new files copied on | Partial. What was overwritten is gone. |
| Stick fully overwritten (zero-fill, secure erase) | None |
| Stick not listed in Disk Utility at all | Software can’t help. A lab might. |
Large files, like long videos, are more likely to come back in pieces than small ones, especially on a stick that was nearly full. Reco marks how intact each file is so you can tell before you save it.
If the stick doesn’t show up
Try another USB port and, if you use one, a different adapter or hub. Then open Disk Utility and choose View ▸ Show All Devices. If the stick is listed there, even grayed out, recover your files before you try to repair it. If it isn’t listed anywhere, macOS can’t read it, and no app can either. For more checks, see when an SD card or USB drive isn’t showing up.
If the stick is dying
Sticks that disconnect mid-copy, slow to a crawl, or show the wrong size are wearing out. Don’t scan them over and over. Use Reco’s Copy first to copy the stick to a disk image once, then scan the copy. You can stop the copy and pick up where you left off.
A stick that reports 0 bytes, or that’s physically snapped at the connector, needs a data recovery lab, not software.
So it doesn’t happen again
- Treat a USB stick as a way to move files, not the only place they live.
- Eject the stick before you pull it out, so nothing is cut off halfway through being written.
- Before you give a stick away, wipe it properly. A normal format leaves files recoverable. See how to securely erase a USB stick.
Questions
Can you recover deleted files from a USB flash drive on a Mac?
Often, yes. USB sticks don’t erase deleted data on their own, so it stays until new files are written over it. Stop saving to the stick and scan it with a recovery app, saving what you find to your Mac.
Where do files deleted from a USB drive go on a Mac?
Files you drag to the Trash from a USB stick stay on the stick, in a hidden Trash folder, and show in the Trash in your Dock only while the stick is plugged in. Plug it back in and check the Trash before anything else.
My USB stick says it needs to be formatted. Can I still get the files?
Usually. Click Ignore rather than Initialize, then scan the stick with a recovery app before you format it. If you already formatted it, see recovering a formatted drive.
Can files be recovered from a USB stick that doesn’t show up at all?
Not with software. If the stick isn’t listed in Disk Utility even with View ▸ Show All Devices, macOS can’t read it, and neither can any recovery app. A data recovery lab can sometimes read the memory chip directly.
