Deleted files, but they are still on the server.

I deleted all folders including the Index Html using the delete key. Cleared the Temporary Internet Files but when going to the site the old one is still there. It was apperently not deleted.

Uploaded new files they are there showing up in the ftp window but when typing the URL the old site shows up.

What am I doing wrong?

A caching server at your ISP or proxy server on your network is storing or caching the old files.

These store web pages on local server(s) to give a faster response to users, and as well to avoid using bandwidth.

Most caches are refreshed every 24 hours, so it may take that long for you to see your new modified web page.
