Chrome extensions are stored in browser configuration files, and the actual files are located in operating system specific folders. The Windows path is C:\Users\YourUsername\AppData\Local\Google\Chrome\UserData\Default\Extensions, macOS is /Users/YourUsername/Library/Application Support/Google/Chrome/Default/Extensions, Linux is /home/YourUsername/.config/google-chrome/Default/Extensions. Each extension has a separate folder named after its unique ID. To find the extension ID, visit chrome://extensions/ and enable "Developer Mode" and the ID will be displayed under the extension name. It is not recommended to edit files directly, as extensions may fail or be overwritten by updates. Debugging should use the "Load Decompressed Extensions" function. Extensions are synced through Google Account, but local files will not be exactly consistent. Chrome automatically manages these files without manual intervention from users unless debugging or researching how the extension works.

Chrome extensions are stored in your browser profile, but if you're looking for the actual files on your computer, they're kept in a specific folder managed by Chrome. The exact location depends on your operating system.

Where to Find Chrome Extensions on Your Computer

If you want to locate the files for installed extensions, here's where they live:

• Windows :
  C:\Users\YourUsername\AppData\Local\Google\Chrome\User Data\Default\Extensions

• macOS :
  /Users/YourUsername/Library/Application Support/Google/Chrome/Default/Extensions

  

• Linux :
  /home/YourUsername/.config/google-chrome/Default/Extensions

Each extension gets its own folder named after its unique ID. Inside, you'll find the extension's code, icons, and other resources. Keep in mind that Chrome may rename or move these files when it updates the extension automatically.

How to Find an Extension's ID

Since the folders have names like "aohghmighlieiainkglofhbkckhgbefo," figuring out which one matches which extension can be tricky. Here's how to find the ID of any extension:

1. Go to chrome://extensions/ in your browser.
2. Turn on “Developer mode” using the toggle at the top right.
3. Look at the list — each extension now shows its ID under its name.

You can use this ID to match the folder name in the file system.

Don't Edit Files Directly

It might be tempting to open up those files and tweak something, but it's not a good idea. Chrome doesn't expect you to modify extensions manually, and doing so can cause them to stop working or get overwritten during an update. If you want to develop or debug an extension, it's better to load it unpacked from the chrome://extensions/ page instead.

Also, note that extensions sync across devices via your Google account, so the same extensions will appear wherever you sign in — but their local files won't be exactly the same unless synched by Chrome itself.

Basically, Chrome handles all of this behind the scenes. You don't need to mess with the files unless you're debugging or inspecting how extensions work.
