How to fix ERROR_INVALID_NAME

Description

The filename, directory name, or volume label syntax is incorrect.

Causes

  • Invalid Characters: The file or directory name contains characters that are not allowed (e.g., \ / : * ? " < > |).
  • Name Too Long: The file or directory name exceeds the maximum length allowed by the file system.
  • Reserved Names: The name used is reserved by the system (e.g., CON, AUX, PRN, NUL).
  • Incorrect Path Format: The file path is incorrectly formatted or contains invalid syntax.
  • Trailing Spaces or Periods: The name ends with spaces or periods, which are not allowed in Windows.

Solutions

Verify and Rename File or Directory

Ensure the name does not contain invalid characters or reserved names. Rename the file or directory by right-clicking it, selecting "Rename," and providing a valid name.

Shorten the File or Directory Name

If the name is too long, shorten it to meet the maximum length allowed by the file system. For example, NTFS supports up to 255 characters for file names.

Correct the File Path

Double-check the file path for any syntax errors or invalid formats. Ensure that the path is correctly structured and does not contain illegal characters.

Remove Trailing Spaces or Periods

Ensure that the file or directory name does not end with spaces or periods. Rename the file to remove any trailing spaces or periods.

Use Unicode or Long Path Tool

For very long file paths, consider using Unicode or specialized long path tools that can handle extended-length paths in Windows. Enable the long path support in Windows 10 by modifying the registry or using Group Policy Editor.

Check for Hidden Characters

Sometimes hidden characters or non-printable characters can cause this error. Use a text editor that can reveal hidden characters to inspect and clean up the file or directory name.

Update Software and Drivers

Ensure all related software and drivers are up-to-date, as updates can fix bugs that might cause naming issues.
