When using Command Prompt or File Explorer to access folders, this problem usually occurs, especially when dealing with files and folders that are synchronized to OneDrive. Let’s investigate this mistake and find out what’s causing it so we can repair it.

Causes of the Error the tag present in the reparse point buffer is invalid

Problems with OneDrive sync are the main source of the problem. If OneDrive isn’t syncing properly, it can be because of a faulty folder or issues with other system files. The two most typical manifestations of this mistake are these:

Both variations of the error stem from similar underlying causes, and therefore, similar fixes can be applied to resolve them.

Before attempting major fixes, it’s essential to perform some preliminary checks:

  • Pause the OneDrive sync and try opening the folder again.
  • Restart your device.
  • Log out of your OneDrive account.
  • If changes were recently made to the problematic folder on OneDrive, revert them temporarily.

If the error persists after these checks, proceed with the following solutions.

Solution 1: Run a CHKDSK Scan

  1. Open Command Prompt as an administrator.
  2. Type Chkdsk C: /f /r (replace C: with the appropriate drive letter) and press Enter.
  3. Allow the scan to complete. This scan can help fix errors, locate bad sectors, and recover corrupted information.

Solution 2: Run the DISM and SFC Scan

  1. Open Command Prompt as an administrator.
  2. Run the System File Checker (SFC) scan by typing SFC /scannow and pressing Enter.
  3. If the SFC scan doesn’t resolve the issue, run the Deployment Image Servicing and Management (DISM) scan by typing DISM /Online /Cleanup-Image /RestoreHealth and pressing Enter.

Solution 3: Check for File-Specific Issues

  • Determine if the error occurs for a specific file or all files synced on OneDrive.
  • Try to replicate the issue with a different folder.
  • If the issue is file-specific, restore the file to its previous version if possible.

Solution 4: Remove Passwords From Problematic Files

  • If the error occurred after password-protecting a file on OneDrive, check the file’s history and restore it to a previous version.
  • Reset OneDrive if necessary.
