OneDrive is a convenient cloud storage service integrated into Windows 11. However, sometimes users encounter the “Name or Type Isn’t Allowed” error. This error can stop you from saving or syncing files properly.

Understanding why this happens and how to fix it can save you time and frustration. The solutions are usually straightforward and don’t require advanced technical skills.

In this article, we will guide you through simple, step-by-step methods to resolve this OneDrive error. Each step includes clear explanations so you know what and why you are doing it.

By the end, you should be able to fix the issue and get OneDrive working smoothly again.

Quick Note Before You Begin

Before diving into the solutions, make sure of the following to avoid unnecessary troubleshooting:

• Check your file name: OneDrive doesn’t support certain characters in file or folder names, like /:*?"<>|. Also, names cannot end with a space or period.
• File type support: Some file types may be restricted or blocked by OneDrive policies.
• Internet connection: Ensure you have a stable connection, as syncing requires internet access.
• Windows updates: Keep your Windows 11 updated for better OneDrive compatibility.

Step 1: Rename the File or Folder

Often, the easiest fix is to rename the file or folder causing the problem. OneDrive restricts certain characters and formats in names.

To rename a file or folder:

1. Locate the file or folder that triggers the error in the OneDrive folder.
2. Right-click on it and select Rename.
3. Remove any special characters such as /:*?"<>| or trailing spaces/periods.
4. Use only letters, numbers, dashes, or underscores in the new name.
5. Press Enter to save the new name.

After renaming, OneDrive should sync the item without errors. This step is important because OneDrive enforces naming rules to maintain file system stability across devices.

Step 2: Check File Path Length

OneDrive has a limit on the total file path length, including folder names. If the file path is too long, it can cause errors.

To check and fix this:

1. Right-click the file or folder and select Properties.
2. Look at the Location and add the length of the file name.
3. If the total exceeds 255 characters, shorten folder or file names.
4. Move files to a location closer to the root folder (e.g., directly inside OneDrive folder).

Shortening paths helps OneDrive handle files correctly, avoiding errors related to Windows file system limits.

Step 3: Clear OneDrive Cache

Sometimes cached data in OneDrive can cause syncing problems. Clearing the cache refreshes OneDrive’s local settings and can fix the error.

Here’s how to clear OneDrive cache:

1. Close OneDrive by right-clicking the OneDrive icon in the system tray and selecting Close OneDrive.
2. Press Win + R to open the Run dialog.
3. Type %localappdata%MicrosoftOneDriveonedrive.exe /reset and press Enter.
4. Wait a few moments for OneDrive to reset and restart automatically.

If OneDrive does not restart on its own, open it manually from the Start menu. Resetting helps clear corrupted cache files that might block syncing.

Step 4: Update OneDrive

Using an outdated version of OneDrive can cause compatibility issues and errors. Make sure your OneDrive app is up to date.

To update OneDrive:

1. Open the Microsoft Store app.
2. Search for Microsoft OneDrive.
3. If an update is available, click Update.
4. Restart your computer after updating.

Keeping OneDrive updated ensures you have the latest bug fixes and improvements, which can resolve unexpected errors.

Step 5: Unlink and Relink Your OneDrive Account

If the problem persists, unlinking and relinking your OneDrive account can refresh your synchronization settings.

To do this:

1. Click the OneDrive icon in the system tray.
2. Select Help & Settings (gear icon) > Settings.
3. Go to the Account tab.
4. Click Unlink this PC.
5. Confirm and follow the prompts to sign out.
6. After unlinking, sign back in with your Microsoft account and set up OneDrive again.

This process resets your OneDrive configuration and often resolves syncing conflicts.

Alternative and Advanced Options

If the above steps do not work, you may consider these options:

• Use the OneDrive Troubleshooter: Microsoft offers a dedicated troubleshooter that can detect and fix common OneDrive issues. Search for “OneDrive troubleshooter” on Microsoft’s official support site.
• Check Group Policy Settings: If you are on a work or school PC, restrictions set by administrators might block certain file types or names.
• Reinstall OneDrive: Uninstalling and reinstalling the OneDrive app can fix corrupted installations.
