You can't and shouldn't like that.

Firstly, LPCWSTR stands for "Long Pointer to Constant Wide String". Key word here is constant. Which means you can't modify it.

Secondly, it points to a string literal, which might be placed in read-only memory. Writing to that to append characters (e.g. using wcscat) could result in your program crashing.

Instead, use std::wstring:

std::wstring modelloc(L"MP_Urban");
modelloc += L".X";



Works exactly like you want.
