#define PATH "C:\\Program Files\\My"
#define FILE "file.txt"

#define HTML 23

file.txt HTML PATH+"\\"+FILE      <--- how to write properly?

You might try it the C style, so just writing

PATH "\\" FILE

but I do not really expect it to work. Even if that is accepted by the resource compiler I doubt that the Resource Editor will accept such code.
