attrib -r -s -h: Why Your Files Disappeared and How to Get Them Back

You’re staring at a USB drive that says it’s full, but the folder looks empty. It's frustrating. You know the data is there, but Windows acts like it’s a ghost town. This isn't usually a hardware failure; it’s often the work of a script or a bit of old-school malware that messed with your file attributes. This is where the command attrib -r -s -h comes into play. It’s basically a skeleton key for the Windows file system.

Most people panic. They think they need expensive recovery software or a trip to a repair shop. Honestly? You probably just need to talk to the Command Prompt for thirty seconds. Windows has these little flags—attributes—attached to every single file. Sometimes those flags get toggled the wrong way.

What is attrib -r -s -h actually doing?

To understand the fix, you’ve gotta understand the flags. Windows uses specific letters to categorize how a file behaves. When you type attrib -r -s -h, you are issuing a blunt directive to the operating system to strip away restrictions.

The -r part stands for "Read-only." When a file has the 'R' attribute, you can look at it, but you can’t change it. By using the minus sign, you're telling Windows to remove that restriction. It’s liberation for your data.

Then there’s -s. This is the "System" attribute. This is a big deal. Windows treats system files with extreme caution because if you delete a real one, your computer might not boot. However, malware loves to "promote" your personal photos or documents to "System" status. Why? Because Windows hides system files by default. If your folder looks empty, it’s likely because your files have been tagged as part of the operating system.

Finally, the -h removes the "Hidden" attribute. This is the most common culprit. It’s the digital equivalent of putting an invisibility cloak over a folder. When you combine them into attrib -r -s -h, you are essentially saying: "Stop protecting this, stop treating it as a system file, and stop hiding it from me."

The Syntax Matters More Than You Think

You can't just type those letters and hope for the best. You need to tell Windows where to look. Usually, people are dealing with an external drive, like a 'G' or 'F' drive.

If you just run the command on a single file, it's fine. But usually, you have an entire drive’s worth of data that has gone missing. That is when you need the "switches." Specifically, /s and /d.

The /s tells the command to look through every single subfolder. If you don't use this, you only fix the files sitting in the root directory, leaving everything else invisible. The /d tells the command to include folders in the process. Without it, you might unhide the files inside a folder, but the folder itself stays invisible. It’s a bit like opening the box but forgetting to take the lid off.

A standard "save my drive" command usually looks like this:
attrib -r -s -h /s /d G:\*.*

Note the *.* at the end. That’s a wildcard. It means "every file name with every file extension." You’re casting a wide net. It’s powerful, but you have to be careful. You don't want to run this on your C:\Windows folder. If you strip the system and hidden attributes from actual Windows OS files, you’re stripping away the safety bumpers that prevent accidental deletion of critical boot files. Stick to your data drives.

Why Do Files Get Hidden Anyway?

It’s rarely a glitch. Most of the time, it's a remnant of a "shortcut virus."

These things were rampant a few years ago and still pop up on school or office computers where USB drives move from machine to machine. The virus doesn't actually delete your stuff because that would be too obvious. Instead, it moves your files into a hidden folder, changes their attributes using the very system we're talking about, and creates a "shortcut" that looks like your folder. When you click the shortcut, it runs the virus and then opens your folder so you don't suspect anything.

Even after your antivirus kills the virus, the attributes remain. The virus is gone, but the "invisibility cloak" stays on. Your antivirus isn't a file manager; it won't necessarily "unhide" your stuff for you. You have to go in and manually do the cleanup.

I've seen people spend hours scanning with Malwarebytes or Norton, and while the scan comes back clean, the drive still looks empty. It's a classic case of the symptoms outlasting the disease.

Step-by-Step: Using the Command Prompt Safely

Don't just copy-paste. Understand the flow.

1. Open Command Prompt as Administrator. Hit the Windows key, type "cmd," right-click it, and choose "Run as Administrator." This gives you the "permissions" needed to override system flags.
2. Identify your drive letter. Open "This PC" and look at your USB or external drive. Is it D, E, F? Let’s assume it’s F for this example.
3. Navigate to the drive. Type F: and hit Enter. Now your command line should show F:>. This ensures you aren't accidentally messing with your main hard drive.
4. Run the master command. Type attrib -r -s -h /s /d *.* and hit Enter.

Now, wait. If there are thousands of files, it won't happen instantly. The cursor will just blink. Don't close the window. When the F:> prompt reappears, the job is done. Go back to your file explorer. Your files should be sitting there, perhaps looking a bit "faded" or just appearing out of thin air.

Common Errors and What They Mean

Sometimes you’ll get an "Access Denied" message. This is annoying but usually fixable. It happens because a process is still using those files, or you don't have ownership of the folder. If you see this, make sure you closed any programs that might be trying to read the drive.

Another common one is "Not resetting system file." This happens when you try to change a file that Windows is particularly protective of. If you get this on a few files while the rest recover, don't sweat it. Those are likely actual system files (like the Recycle Bin folder or System Volume Information) that you shouldn't be messing with anyway.

Is There a GUI Way to Do This?

Yes, but it's clunky. You can go into Folder Options, click the "View" tab, and check "Show hidden files, folders, and drives" and uncheck "Hide protected operating system files."

But here’s the catch: that only lets you see them on that computer. It doesn't actually fix the files. If you take that USB to a friend's house or a print shop, the files will be "gone" again. Using attrib -r -s -h is a permanent fix. It changes the files themselves, not just how your specific computer looks at them. It’s the difference between wearing X-ray specs and actually opening the door.

Beyond the USB Drive: Other Uses

While the USB recovery is the "hero use case," this command is a staple for power users. Developers sometimes use it to reveal hidden configuration files like .htaccess or .git folders that might be hidden by default in certain environments.

It’s also useful for cleaning up "stubborn" files that refuse to be deleted because they are marked as Read-only. If you have a folder that keeps saying "You do not have permission to delete this," hitting it with a quick -r flag often solves the problem instantly.

Safety and Best Practices

Power comes with a bit of risk. The attrib command is a legacy tool—it’s been around since the DOS days. It doesn't have a "confirm" button. It just does what you tell it to do.

• Check the drive letter twice. If you run this on C:\, you’re going to make a lot of sensitive system files visible and vulnerable.
• Don't use it on Cloud folders. If you run this on a synced Dropbox or OneDrive folder, it can sometimes trigger a massive re-sync because the metadata of every single file just changed.
• Backup first if you can. If the drive is failing (clicking noises, slow transfer), don't run commands. Use a disk imaging tool. attrib is for logical issues (software/attributes), not physical ones.

Once you’ve run the command and your files are back, your first move shouldn't be to celebrate. It should be to scan that drive with a dedicated malware scanner. Remember, something changed those attributes in the first place. Whether it was a script you ran or a worm you picked up, you need to find the source so you don't have to run the command again tomorrow.

Practical Next Steps

Now that you understand the mechanics, here is how to handle a "missing" file situation moving forward:

1. Confirm it’s an attribute issue: Check the drive properties. If "Used Space" shows 10GB but the folder looks empty, you are 100% dealing with hidden attributes.
2. Target the specific directory: If you don't want to run it on the whole drive, navigate to the specific folder in CMD using the cd command before running attrib.
3. Re-hide if necessary: If you accidentally unhide things like desktop.ini or autorun.inf and they're cluttering your view, you can put the cloak back on by using the plus sign: attrib +h +s filename.
4. Format for a fresh start: Once your data is safely backed up to a different location, the best way to ensure a USB drive is "clean" from attribute-flipping malware is to perform a full format (not a quick format) to NTFS or exFAT.
