I accidentally deleted important files from my USB flash drive on a Windows PC, and I need to recover them as soon as possible. The drive had work documents and personal photos that weren’t backed up, and I’m worried using it more could overwrite the data. What are the best ways to recover deleted files from a flash drive on Windows?
I’d start with data recovery software, as long as the USB stick still shows up like a normal drive. If it is missing from the system, reports 0 bytes, drops connection every few seconds, or gets hot for no good reason, I’d stop there. Those cases feel more like hardware trouble, and software tends to waste time. If this was a plain file deletion, software gives you the best shot without turning it into an expensive lab job.
First thing, and yeah, this part matters most, stop writing anything to the USB right now. Don’t move files onto it. Don’t format it. Don’t try to tidy folders. On USB drives, deleted stuff usually does not sit in the normal Recycle Bin. The file system marks the old space as free, and once new data lands there, the old files get overwritten. After tha, recovery odds drop fast.
Before you scan, I’d check the boring stuff once. I’ve seen people think files were deleted when they were hidden, renamed, or copied somewhere else earlier.
Show hidden files on the USB.
Look for folders named $RECYCLE.BIN, RECYCLER, RECYCLED, or .Trashes if the drive touched a Mac.
Check your PC folders, especially Downloads, Desktop, Documents, and any folder where you usually drag stuff in a hurry.
Look through backups and sync folders like OneDrive, Google Drive, Dropbox, or File History.
If none of that turns up anything, I’d move to recovery software.
The tools differ in how they scan, how much they preview, what file systems they handle, and how annoying the interface feels. The workflow is close enough across most of them:
Install the software on your computer, not on the USB drive.
Connect the USB and pick it inside the recovery tool.
Run a deleted or lost file scan.
Let the scan finish. If the files matter, don’t cut it short.
Filter by type, date, size, or filename if the program supports it.
Preview files when the option exists.
Select what you need.
Save recovered files to your computer or another drive, never back onto the same USB.
I learned this one the annoying way years ago. Writing recovered files back to the same stick risks overwriting other deleted data you have not recovered yet. Once you do that, you’ve cut off your own second attempt.
These are the tools I’d look at first:
Disk Drill
This is the one I’d try first for a normal deleted-file case. It supports FAT32, exFAT, and NTFS, which covers most USB sticks people bring up. The layout is easy to figure out, and the preview feature helps a lot. If a photo or document previews cleanly, I usually take that as a good sign before restoring it. I’ve also seen it do better than expected when the file system looked a bit messed up.PhotoRec
Free, ugly, effective. That’s my short version. It shines when the file system is damaged or missing, but it often dumps recovered files without original names or folder structure. So you end up sorting a mess of files by hand. I’d keep it as the backup plan when prettier tools strike out.Data Rescue
It works fine from what I’ve seen, though I never liked the interface much. Stuff feels less obvious than it should. Still usable, and worth a second pass if the first tool misses something.Recuva
Still worth mentioning for simple Windows jobs. It’s older and more limited, and I would not expect miracles with odd formats or messy file system damage. For common files like JPG, PDF, DOCX, and other basic stuff, it still gets results often enough.
One thing I would not touch at the start is CHKDSK, or any repair command in the same lane. Those tools try to fix file system issues. They are not built for undeleting files. Sometimes they help a damaged drive mount properly. Other times they rearrange things and make recovery harder. My order is simple, recover first, repair later.
So if your USB still mounts normally, I’d scan it with Disk Drill first, recover the important files to another drive, then deal with cleanup or reuse after. If the drive feels unstable in a physical sense, disconnects, heats up, or disappears, I’d skip home fixes and send it to a recovery lab instead.

If the flash drive still shows the right size in Windows, I’d make an image of it first, then recover from the image. I differ a bit from @mikeappsreviewer there. Scanning the original USB is fine for simple cases, but cheap sticks love to flake out mid-scan. A byte-for-byte copy gives you a safer second shot.
What I’d do:
- Plug it in once and check Disk Management.
- If it shows healthy capacity, clone it with a tool like USB Image Tool or HDD Raw Copy.
- Run recovery on the image file, not the stick.
- Start with Disk Drill, since it handles deleted docs and photos well on exFAT, FAT32, and NTFS.
- Sort results by original folder path first, then file type. This saves a ton of time.
- Recover the most important files first, work docs before bulk photos.
- Open a sample of each recovered file right away. Don’t wait till later and find out half are corrupt.
One place people miss, Office temp files and thumbnail caches on the PC. If you opened those files before deletion, search your Windows drive for .tmp, .asd, .wbk, and recent-file lists. Photos sometimes survive in app caches too.
If the drive asks to format, don’t do it. If it drops offline or reads 0 bytes, stop messing with it. That’s where home recovery gets riskey fast.
Also, if you want a quick visual walkthrough, this Facebook video guide for flash drive file recovery on Windows is easier to follow than a wall of text.
I’d add one thing neither @mikeappsreviewer nor @voyageurdubois really stressed enough: check whether the files were deleted from the USB through an app, not plain File Explorer. Some programs save edited copies to the PC and only remove the removable-drive version, which makes it look like total loss when it isn’t.
A few extra places to check on Windows before doing recovery:
- Word/Excel auto-recovery folders
- Recent Files in Office apps
- Windows Search with part of the filename
- File History or Previous Versions on folders where you may have copied them before
- OneDrive web recycle bin if those docs were ever synced
- Photos app import folder, because people forget they already imported pics months ago
I slightly disagree with the “always image first” advice. For a cheap healthy flash drive, sometimes a direct scan is faster and fine. If the stick is acting weird, then yes, clone first. If it’s stable, I wouldn’t overcomplicate it.
Also, avoid “fixing” the drive permissions, assigning random drive letters, or running those sketchy “USB repair” tools from Google. That stuff can make a simple delete case uglier real fast.
For actual recovery, Disk Drill is a solid first shot on Windows because it’s easy to sort documents and photos without digging through nonsense forever. If filenames matter, try that before file-carving tools. Then verify the recovered files actually open, not just that they exist. Big diff there.

best USB recovery software recommendations for Windows flash drives
Main thing: don’t use the USB anymore. Every minute of “just checking stuff” can make recovery worse. Been there, did the dumb thing, regretted it lol.
One angle I’d add: check Windows Security / antivirus quarantine before doing recovery. I’ve seen USB docs and photos “disappear” because Defender flagged a macro doc or autorun junk and moved nearby files into quarantine confusion. Also check Event Viewer for disk errors. If you’re seeing repeated I/O or controller resets, I disagree with doing long scans at all until you’ve copied what you can.
If the stick is stable, Disk Drill is a sensible first pass because it keeps filenames and folders better than carving-only tools.
Pros of Disk Drill
- Easy previews
- Good for FAT32/exFAT/NTFS flash drives
- Better file organization than barebones tools
Cons
- Free recovery is limited on Windows
- Deep scans can return lots of junk
- Not ideal for physically failing USB hardware
I’m with @voyageurdubois on being cautious, but not every healthy stick needs imaging first. And I agree with @codecrafter and @mikeappsreviewer on checking Office autosaves and cloud folders, though I’d do quarantine and SMART-like error clues first. If files are critical, recover the smallest irreplaceable docs first, then photos after.
