If you are seeing a “Not-Valid-Name” error in OneDrive on your Windows 11 computer, it usually means there is an issue with the file or folder name you are trying to sync. This error prevents OneDrive from syncing your files properly.
OneDrive has specific rules about which characters and formats are allowed in file and folder names. When these rules are not followed, you may encounter this error.
The good news is that fixing this error is straightforward once you understand what causes it. This guide will help you resolve the issue step-by-step.
By following these simple instructions, you can get your OneDrive syncing again without losing any important data.
Quick Note
Before starting, make sure:
- Your Windows 11 is up to date with the latest updates installed.
- You have a stable internet connection since OneDrive needs it to sync files.
- You are signed into OneDrive with the correct Microsoft account.
- OneDrive is running and properly set up on your PC.
Step 1: Identify the Problematic File or Folder
The first step is to find which file or folder is causing the “Not-Valid-Name” error. Usually, OneDrive will show an error icon next to the file or folder.
Look for any files or folders with a red “X” or warning icon in your OneDrive folder. Note their names carefully.
This is important because fixing the wrong file will not solve the problem. Knowing the exact file or folder will help you proceed with the correct action.
Step 2: Rename the File or Folder with Allowed Characters
OneDrive does not allow certain characters in file or folder names. These characters include:
/ : * ? " < > | # % { } &
Rename the problematic file or folder to remove any of these characters. To rename:
- Right-click the file or folder.
- Select Rename from the menu.
- Change the name by deleting any forbidden characters.
- Press Enter to save the new name.
After renaming, OneDrive should be able to sync the file or folder without issues.
Step 3: Check for File Name Length Limits
Another common cause is that the file or folder name is too long. OneDrive supports file paths up to 400 characters.
If your file is deep inside many folders, the full path might exceed this limit.
To fix this:
- Try moving the file or folder closer to the root of your OneDrive folder.
- Shorten folder or file names to reduce the overall path length.
This helps OneDrive process the file without errors.
Step 4: Remove Unsupported File Types
Some file types may not be supported by OneDrive and can cause sync errors.
Check if the file extension is one that OneDrive supports. Common unsupported files include temporary or system files.
If you find an unsupported file:
- Move it outside of the OneDrive folder.
- Alternatively, delete it if it is not needed.
Step 5: Clear OneDrive Cache
Sometimes OneDrive’s cache might cause syncing errors. Clearing the cache can help reset file sync status.
To clear OneDrive cache:
- Close OneDrive by right-clicking the OneDrive icon in the system tray and selecting Close OneDrive.
- Press
Win + Rto open the Run dialog. - Type
%localappdata%MicrosoftOneDriveonedrive.exe /resetand press Enter. - Wait a few minutes for OneDrive to reset and restart automatically.
This process refreshes OneDrive and can fix many sync problems.
Step 6: Use the OneDrive Troubleshooter
Windows 11 includes a built-in troubleshooter for OneDrive that can automatically detect and fix common issues.
To run the troubleshooter:
- Open Settings by pressing
Win + I. - Go to System > Troubleshoot > Other troubleshooters.
- Find Microsoft OneDrive and click Run next to it.
- Follow the on-screen instructions to complete the troubleshooting process.
This tool can help fix errors you might not be able to spot manually.
Alternative Methods and Advanced Options
Manually Sync OneDrive
If OneDrive is stuck, you can try forcing a manual sync:
- Right-click the OneDrive icon in the system tray.
- Click Sync or Resume syncing if available.
This might help push through files that were previously blocked.
Reinstall OneDrive
When all else fails, reinstalling OneDrive can resolve deeper software issues.
- Press
Win + Ito open Settings. - Go to Apps > Installed apps.
- Find and select Microsoft OneDrive.
- Click Uninstall and follow the prompts.
- After uninstalling, download the latest OneDrive version from the official Microsoft OneDrive site and install it.
