where is the webserver and index.html file located ?

[DJ Crazy Jimmy]

i have Shoutcast Server v2.6.0.753/win64 running on my machine i pointed my domain at my server here i keep at home and wanted to know where can i find the index.html file on the server so i can modify it or look in the directory. I looked for a few hours but could not find it. Also i want to know is there a robots.txt file on the web server for shoutcast so i can modify that as well i put site ownership in my domain txt file but google says there is a robots.txt file that won't index the server currently. I don't know where it is located. thanks in advance for a response to both questions.
