Quick Note: Prerequisites and Basic Checks
Before you begin troubleshooting, make sure of the following:
- You have basic access to your Windows 11 device and can open the app or program where you are creating the notebook.
- The notebook name you want to use does not contain any special characters like
/ : * ? " < > |. These characters are not allowed in file or folder names on Windows. - Your Windows 11 system is up to date. Sometimes errors are fixed with system updates.
- You have sufficient permissions to create or rename notebooks in the app or folder you are working in.
Step 1: Check and Remove Invalid Characters from the Notebook Name
The most common cause of the invalid notebook name error is the use of forbidden characters. Windows does not allow certain symbols in file or folder names. These include:
(backslash)/(forward slash):(colon)*(asterisk)?(question mark)"(quotation marks)<(less than)>(greater than)|(vertical bar or pipe)
How to fix: When naming your notebook, avoid all these characters. Use only letters, numbers, spaces, hyphens (-), or underscores (_). For example, instead of naming your notebook My:Notes?, use My Notes or My_Notes.
Step 2: Keep the Notebook Name Short and Simple
Windows has a limit on how long file and folder names can be. If your notebook name is very long, it may trigger the invalid name error.
How to fix: Try to keep the notebook name under 50 characters. Simple and concise names are also easier to organize and find later.
Step 3: Avoid Using Only Spaces or Periods in the Name
Sometimes, if your notebook name is just spaces or ends with a period (.), Windows will not accept it.
How to fix: Make sure your notebook name contains actual visible characters like letters or numbers, and does not start or end with a space or period.
Step 4: Rename the Notebook Using File Explorer (If Applicable)
If you are creating or renaming a notebook that is saved as a file or folder on your computer, you can rename it directly from File Explorer.
How to do this:
- Open File Explorer by clicking the folder icon on your taskbar or pressing
Windows + E. - Navigate to the folder where your notebook is saved.
- Right-click the notebook file or folder and select Rename.
- Type a new name that follows the rules mentioned above (no invalid characters, not too long).
- Press
Enterto save the new name.
This method helps bypass app-specific restrictions by renaming at the file system level.
Step 5: Restart the App or Your Computer
Sometimes, the error occurs due to temporary glitches or bugs in the app or system.
How to fix: Close the app completely and reopen it. If that does not help, restart your computer to refresh Windows 11 processes.
Step 6: Update Windows 11 and the Relevant App
Software updates often fix bugs that cause errors like invalid notebook names.
How to update Windows 11:
- Click the Start button and select Settings.
- Go to Windows Update.
- Click Check for updates and install any available updates.
How to update the app: Open the Microsoft Store or the app’s update mechanism and install the latest version.
Advanced Option: Create the Notebook in a Different Location
If you continue to get the invalid notebook name error, try saving or creating the notebook in a different folder or drive. Sometimes, permission issues or folder restrictions cause naming errors.
How to do this: When creating the notebook, select a different folder, such as your Documents folder or another drive with write access.

What if I still can’t rename the notebook after following these steps?
This might indicate a permissions issue or corruption. Try running the app as an administrator or check for disk errors on your storage drive.
