Hi Giuseppe, ok then its not a TMS but a Google style XYZ tileset. In ArcBruTile the tiles are retrieved using HTTP protocol, so a webserver is required. Caddyserver works also on windows yes.
if you have caddy 1.x installed, its just going to a directory and start caddy from commandline ($ caddy). A webserver on port 2015 will start, in a browser go to http://localhost:2015/ to retrieve files from that directory. I believe in Caddy 2.0 its changed a bit.
