Err File Not Found error On Chrome

The Err_File_Not_Found error is a common issue that Google Chrome users may encounter while browsing the web or developing Chrome extensions. This comprehensive guide will help you understand the causes of this error and provide step-by-step solutions to resolve it effectively.

Introduction to Err_File_Not_Found

Err File Not Found Error

The Err_File_Not_Found error occurs when Google Chrome is unable to locate a specific file necessary to display a webpage or run an extension. This error is unique to Chrome and is similar to the well-known 404 error, but it often points to issues within the browser itself rather than problems on the server side.

Users typically encounter this error in the following scenarios:

  • When trying to access local HTML files
  • While using certain Chrome extensions
  • During the development and testing of Chrome extensions
  • When attempting to open files with incorrect paths

The impact of this error can range from minor inconveniences to significant disruptions in workflow, especially for developers working on Chrome extensions.

Common Causes of Err_File_Not_Found

Understanding the root causes of the Err_File_Not_Found error is crucial for effective troubleshooting. Here are the most common reasons this error occurs:

  1. Missing or Deleted Files: The file Chrome is trying to access may have been moved, deleted, or renamed.
  2. Incorrect File Paths: Mistakes in file paths, especially when dealing with local files, can lead to this error.
  3. Issues with Browser Extensions: Faulty, outdated, or conflicting extensions can cause Chrome to fail in locating necessary files.
  4. Corrupted Browser Data: Corrupted cache, cookies, or other temporary data can interfere with Chrome’s file access.
  5. Network Connectivity Problems: Unstable or restricted network connections can sometimes result in file access issues.

How to Fix Err_File_Not_Found Error

Let’s explore various methods to resolve the Err_File_Not_Found error, starting with the simplest solutions and progressing to more advanced troubleshooting techniques.

3.1 Disable Chrome Extensions

  4. After disabling an extension, refresh the page to see if the error persists.
  5. If the error disappears after disabling a specific extension, you’ve identified the problematic one.

3.2 Remove Problematic Extensions

If disabling extensions doesn’t work, try removing persistent extensions:

  2. Delete folders of extensions you’ve previously uninstalled but may still be causing issues.
  3. Restart Chrome and check if the error is resolved.

This will disable all extensions and delete temporary data, often resolving the error.
