How to get file name or path in vscode extension when user right click on file in explorer/context?

Question

My extension creates a context menu in the explorer tree:

\"contributes\": {
        \"commands\": [
            ...         


        

Answer 1

The callback will receive an argument with a vscode.Uri object:

vscode.commands.registerCommand('myextension.mycommand', (uri:vscode.Uri) => {
    console.log(uri.fsPath);
});
