I'm guessing you are using a CMS NewPoker and that is why this seems like a strange concept. you may be updating your content via the web browser and not locally on your comouter and then uploading it.
If you're using Firefox you need the
FTP extension. just search Gogle for Fire fox
FTP extension.
If you have IE and it's NOT version 7 we are ok. Just type the
FTP address of your site. like:
ftp.pokersite.com
Then you put in your username and password from your host and just copy and paste it in there.
If you are using IE7 and don't have FF or the
FTP extension you can do this through windows command promtp too. Same thing type the
FTP address of your site supply credintials and then use DOS commands to copy it over. Sounds hard huh?
Otherwise your host should have some access to your files within your Cpanel. What host are you using?
