A read-only document can’t be edited, but what if all your documents are set to read-only? This can be a problem we will tackle in today’s article.

This is how one user described the issue on Superuser forums:

Restarting my computer one day, most of my files in my folders were switched to read-only. I’ve changed the permissions to allow everyone full control, as well as going through each user.

While read-only files can be helpful, sometimes your documents can become read-only, which can be an issue. In this article, we’ll try to show you how to fix this problem.

Why are all of my files read-only?

Here are a few reasons why all of your files might be marked as read-only. A few possible reasons could be the following:

  • File settings – Your files were set to read-only mode by mistake or third-party software, especially antivirus.
  • PC settings – Your computer’s operating system or security settings prevent you from modifying or deleting the files.
  • Device type – Your files are stored on a read-only device, such as a CD or DVD.
  • File damage – The file system on your hard drive may have become corrupt or damaged, causing all files to be marked as read-only.
  • Permission issues – Your user account may not have the necessary permissions to modify or delete the files.
