Why does Windows show my file names in green letters?

File names appearing in green letters are encrypted.Q: My friend sent me a folder with zipped files.

When I opened it on my computer, Windows showed the files’ names in green letters, rather than the normal black.

And when I tried to copy the zipped folder, Windows sent me this error message:

“Confirm Encryption Loss. Do you want to copy this folder without encryption? A problem is preventing this folder from being encrypted.”

What am I doing wrong?

A: Displaying file names in green letters, as shown above, is Windows’ way of telling you that those files are encrypted: They’re encoded to keep out snoops.

When Windows thinks a file is encrypted, it sometimes sends out odd error messages like the one below:

Do you want to copy this folder without encryption? A problem is preventing this folder from being encrypted.

But the confusion can be cured quite easily. Turn the names back to black and avoid that error message by following these steps:

  1. Right-click the green-lettered file or folder and choose Properties.
  2. When the Properties window appears, click the Advanced button.
  3. Click to remove the checkmark from the box called, “Encrypt Contents To Secure Data,” shown below, and click the OK button.

Click to remove the checkmark next to the words, "Encrypt contents to secure data."

 

The letters return to their normal black, and you can share them with others without problem.

Why did this even happen?

This didn’t happen because of a virus, so no worries there. No, this annoying problem usually pops up when dealing with a file that’s been zipped on an Apple computer, then opened with a Windows Vista or Windows 7 computer.

You can tell the zipped file came from an Apple computer if you spot a folder named __MACOSX inside the zipped folder. (That folder can be safely deleted on a Windows PC.)

I have the green filename problem caused by MAC OS/X compression but it won’t go away so easily. The problem is that I unzipped the file(s) a while back and later upgraded the OS to Win8 RC and now I can’t read them. When I try to uncheck the encryption box under Properties/Advanced I am asked for Administrator privileges and then I get an error message saying “Access is Denied”. I presume this is due to the original file/folder being created under a different username in the previous OS version.

I think you are referring to EFS (encryption file system?) rather than BitLocker. As far as I understand, the former is used for encrypting files in the upper versions of Windows and the latter is used for encrypting hard drives (or portable storage devices) in Windows Ultimate and Enterprise.

Thank you so much for this helpful tutorial. I had the “green text” issue with a folder of fonts I had purchased. Every time I tried to install the fonts, a message asked me to overwrite because they were already installed, yet they didn’t show up either in the font dropdown menu or in the font folder within Windows. Your solution was super simple and quick, which is what a nontechie like me needed!

Your answer not correct

“They are encrypted. if you wish to turn the encryption off, right click on the file(s) > Properties > Advanced > un-check “Encrypt Contents To Secure Data”

These are the errors one gets when using Andy’s suggestion

You need administrator permission to change these attributes

continue

An error occured applying these atributes access denied

This only works if you are still using exactly the same user account on the original machine. If your files transfer and you try to open them under a new account it doesn’t matter if your administrator and owner, you cannot break the encryption because the encrypt keys are bound to original account. In other words, you’re screwed.

Comment from Andy Rathbone
Time January 24, 2015 at 2:43 pm

Mitch: That’s true. However, when a PC owners suddenly notice file names with green letters, it’s usually because they’ve unzipped a file that was originally zipped on a Mac. In that case, the steps given here will work.

I can see the file names which are in Green Color in the particular folder. But i couldn’t open the file. Its saying as “Not having proper perimission” But i checked with my Internal IT team, they confirmed that the folder/file name is having full control.

This issue i am facing after installating the 64 bit windows 7 os. Previously, its was 32 bit windows 7.

Please suggest.

Thanks in advance,

Any idea why these files might cause crashes? (on W7 32)

I’ve had a few of these recently, the files look exactly as you describe, with a _macosx folder.
But… they seem to crash every program I touch them with. Explorer, Sublime Text, Dreamweaver…

Only solution has been to delete in safe mode.

Hi Andy, I feel some clarity needs to be injected here, as we still encounter this problem years after your original article was posted – First of all, for some it is clearly as simple as checking the box to unencrypt in the file-properties-advanced options… but there are also some here who had a file sent to them, who found that file came from a Mac system, who tried to open the docs after unzipping which were encrypted according to protocol, who clearly can’t open them because they are not the original owner. I am in that situation, have full administrative privileges on a W2008 server, and can’t take permission from the original owner. So whoever said ‘you’re screwed’ previously was correct. Unless you have ownership or ownership has been removed, you typically cannot access these folders or change their permissions – period. Fortunately I can get back to the original owner and get my documents without zipping them, but others may have to find other creative work-arounds. Good luck to those in that special category who can’t take ownership, and of course I’d LOVE to see a solution that doesn’t pretend that those of us who still have the issue don’t know what we’re talking about. THANKS!

> Andrew: I’m sorry to hear of your situation, but my article simply addresses the issue of why file names are green on some computers. In the majority of cases, the steps described here work. Taking ownership on a file using Windows 2008 Server is beyond the scope of my books, hence I don’t discuss it here. Have you tried this Technet article on Taking Ownership of a File or Folder?
