### Example — Open files in Windows Explorer

> **Note** : As of Mp3tag v3.12, use _File → Open in Explorer_ or the context menu to open files in Windows File Explorer.
> 
> The following is preserved as an example for other file explorers like Total Commander.

**Name**  
e.g., Windows-Explorer

**Path**  
You need to enter the path to `Explorer.exe` here, usually located at `C:\Windows\Explorer.exe`.

**Parameter**  
The parameters of Windows Explorer are always seperated by comma and space,  
e.g., **`/e, /select, "%_path%"`**

**`/e`** opens Windows Explorer in two columns. On the left is the directory tree, on the right the file view. Without this parameter, only the file view will be displayed.

**`/select`** marks the selected file. If there are several files selected in Mp3tag, only one of them will be marked.
