How to fix 'The directory name is invalid' error in Windows Command Prompt?

<p></p> <ol><li>Check the path syntax for correct formatting, proper backslashes, no extra spaces, and typos, using examples like cd C:\Users\YourName\Documents or combining drive and path: C:\Users\YourName\Documents. 2. Verify the target drive exists by checking File Explorer and reconnecting removable drives if necessary. 3. Avoid invalid characters in folder names such as , :, ", |, ?, * and use the ?\ prefix for problematic paths. 4. Handle long file paths exceeding 260 characters by enabling Win32 long paths via Group Policy or Registry, or use the ?\ prefix when navigating. 5. Run Command Prompt as Administrator to resolve potential permission issues. 6. Check for file system corruption using chkdsk C: /f with admin rights, scheduling it if needed. Common mistakes include using cd D: instead of D: alone, incorrect slashes, and assuming disconnected drives are accessible, so always confirm path accuracy, drive availability, and naming compliance to resolve the issue completely.</li></ol> <p><img src="/static/imghw/default1.png" data-src="https://img.php.cn/upload/article/000/000/000/175523268425906.jpg" class="lazy" alt="How to fix \" the directory name is invalid error in windows command prompt></p> <p>The "The directory name is invalid" error in Windows Command Prompt usually appears when you're trying to navigate to or access a directory that doesn’t exist, has an incorrect path, contains invalid characters, or involves a drive that isn’t available.
