Windows 10: Folder Unavailable Error When Trying to Access Folders in File Explorer

Windows 10 Folder Unavailable Error Trying to Access Folders in File Explorer

If you are using the Windows 10 operating system and have recently encountered an error message stating "<:\FOLDER unavailable" when trying to access a folder directly through File Explorer, you are not alone. This error can be frustrating and make it difficult to access the files and folders you need. In this article, we will cover the key concepts related to this error and provide some potential solutions.

Understanding the Error

The "<:\FOLDER unavailable" error in Windows 10 is typically caused by a problem with the permissions set on the folder in question. This can happen for a variety of reasons, such as if the folder has been moved or renamed, if the permissions have been changed manually, or if there is a problem with the Windows 10 operating system itself.

Checking Permissions

The first step in troubleshooting this error is to check the permissions on the folder in question. To do this, right-click on the folder and select "Properties." In the properties window, click on the "Security" tab. Here, you should see a list of the users and groups that have access to the folder. Make sure that your user account is listed and that it has the appropriate permissions (such as "Read" or "Read & Execute").

Taking Ownership of the Folder

If you are still unable to access the folder after checking the permissions, you may need to take ownership of the folder. To do this, right-click on the folder and select "Properties." In the properties window, click on the "Security" tab, then click on the "Advanced" button. In the advanced security settings window, click on the "Change" link next to the "Owner" field. In the select user or group window, type in your user account name and click "Check Names." Then, click "OK" to close the window. Back in the advanced security settings window, check the box next to "Replace owner on subcontainers and objects" and click "OK."

Using the Takeown Command

If taking ownership of the folder through the graphical user interface (GUI) does not work, you can also try using the takeown command in the command prompt. To do this, open the command prompt as an administrator and navigate to the parent folder of the folder in question. Then, type the following command and press enter:

Replace "foldername" with the name of the folder you are trying to take ownership of. The /r switch tells the command to take ownership of all subfolders and files, and the /d y switch confirms that you want to take ownership of the files and folders.

Using the Icacls Command

After taking ownership of the folder, you may still need to set the appropriate permissions. To do this, you can use the icacls command in the command prompt. Open the command prompt as an administrator and navigate to the parent folder of the folder in question. Then, type the following command and press enter:

Replace "foldername" with the name of the folder you are trying to set permissions for, and replace "username" with your user account name. The (OI) and (CI) switches tell the command to apply the permissions to the folder and all of its subfolders and files. The F switch grants full control permissions.

Checking for Operating System Problems

If you have tried all of the above steps and are still unable to access the folder, there may be a problem with the Windows 10 operating system itself. You can try running the system file checker tool (sfc /scannow) to check for and repair any corrupted system files. You can also try performing a clean boot of the operating system to see if any third-party applications are causing the problem.

• The "<:\FOLDER unavailable" error in Windows 10 is typically caused by a problem with the permissions on the folder in question.
• To troubleshoot this error, you should first check the permissions on the folder and make sure that your user account has the appropriate permissions.
• If that does not work, you may need to take ownership of the folder and set the appropriate permissions using the takeown and icacls commands in the command prompt.
• If all else fails, there may be a problem with the Windows 10 operating system itself, and you may need to run the system file checker tool or perform a clean boot to resolve the issue.
