Hey Stevey, different hosts use different "index" files. Here is a list of some examples to try:

1. index.htm
2. index.html
3. index.php
4. default.htm
5. default.html
6. default.php
7. home.htm
8. home.html
9. home.php
10. welcome.htm
11. welcome.html
12. welcome.php
13. base.htm
14. base.html
15. base.php

If the server you're hosted on is a Windows server, you could also try index.asp, index.aspx, default.asp, default.aspx, etc...

The best thing to do would be to search your hosts FAQ. Also, if you have write access to your .htaccess file, try adding "DirectoryIndex index.html" (without the quotes and change html with your preferred extension)

Then, your new index.html will be the default regardless of your hosts setting as your .htaccess file with override the server settings (or should).

Also, be sure you're uploading your index file to the public accessible directory (usually /www or /htdocs or /public_html).

HTH
