2. You don’t have the appropriate permissions
- Right-click the problematic file or folder and click Properties.
- Click the Security tab.
- Under Group or user names, tap or click your name to see your permissions.

- Click the Security.
- Under Group or user names, click your name to see your permissions.
- Click the Edit button.

Permissions determine whether or not you can access or change files and folders. So, for example, if you can’t access your files accompanied by an access denied error message even as an administrator, it might be because you don’t have the read permission for the file.

Encryption protects your files and folders from unauthorized access. If you don’t have the certificate used to encrypt the file or folder, you cannot open it.
4. File or folder may be corrupted
Files can become corrupted for various reasons, but the most common is when you have a file open when your computer crashes or loses power. Unfortunately, you cannot repair most such files, so you should delete or restore the file from a backup copy.
To run a check on file integrity, we recommend Restoro, a multifunctional tool that repairs most issues on your computer.
Restoro scans your PC, finds any corrupted or damaged files, and replaces them with the original and untouched version of that file. It uses a database of over 25 million Windows files to make sure that no issue can be left unresolved.
Run a checkup to see how you can improve your system.

Sometimes Windows may not correctly read your local user profile, which means you may lose access to your files and folders. In this case, you must create a new user profile, so you need a new local user account. This should fix the can’t access folders and files issue.
