5 Ways to Fix the ERROR_INVALID_NAME

The ERROR_INVALID_NAME typically occurs in Windows systems when an app or operation encounters a file or directory name that is not valid.

First, determine when the error occurs, whether during file operations, application installation, or any other action. Then, closely check the error message, which can tell you about the file or directory causing the issue.

How can I get rid of the ERROR_INVALID_NAME?

1. Check file/directory name

Windows doesn’t allow certain characters in file or directory names, including \ / : * ? ” < > | so make sure you don’t use any of these. Also, refrain from using reserved names like CON, PRN, AUX, NUL, COM1 to COM9, LPT1 to LPT9.

If you can access the file/directory, right-click it, choose Rename, and remove invalid characters or reserved names. Also, ensure the total path length is less than 260 characters.

2. Check the permissions

1. Right-click the problematic drive or file and select Properties from the context menu.
2. Go to the Security tab. You will see a list of groups and user names that have permission to access the drive or file. Look for your user account or the group you belong to and select it.
3. Now, under Permissions for (User Account Name), you will see:
   • Full Control: Complete control over the file/folder.
   • Modify: Allows you to edit and delete the file/folder.
   • Read & Execute: View and execute file but can’t modify/delete it.
   • Read: Can only view the file/folder.
   • Write: Can add files & subfolders but not delete existing ones.
4. If you need to change permissions, you can click the Edit button.
5. On the Permissions window, find your user account in the list, and check or uncheck the Permissions that you want to change. If you select Full Control to give complete control over the file, then click Apply, then OK to save the changes.
6. Click OK to close the window.

If you don’t see your user account in the list of groups and user names, you need to add it. For that, follow these steps:

1. In the Permissions window, click the Add button.
2. In the Enter the object names to select field, enter the user name and click Check Names to validate it.
3. After adding your account, it will appear in the list; then you can set the desired permissions.
4. Once done, click Apply and OK twice to save the changes.

5. Type the following command to list all files and folders in the drive, then hit Enter: dir
