That is correct. The frx (or ctx) is just a collection of binary and binary string data (like multi lines property of TextBox), and the frm stores the binary address of the point where the data starts, for example this is the Picture of a Options button:

Picture = "frmOptions.frx":014A

That tells the compiler that the image for the button can be found at address 0x14A of the corresponding frx file
As long as these entry points are left alone, you can modify the frm in notepad (pretty much) safely
