## Where to Save the Add-In File? {#where-to-save-the-add-in-file}

The Add-In file (.xlam) must be saved in the correct location for Excel to recognize it automatically.

**Windows**

Save the `.xlam` file to:

```
C:\Users\<User>\AppData\Roaming\Microsoft\AddIns
```

!!!secondary
The AppData folder is hidden by default. To reveal it, open File Explorer, go to the View tab, and check **Hidden items**.

After copying the file, right-click it, select **Properties**, and click **Unblock** if the option appears. This ensures Windows does not block the file from running.

Save the `.xlam` file to:

```

You can save the file to a different location, but you will need to browse manually to that location when enabling the Add-In in Excel.
