Should I delete the default GoDaddy files?

Hi Everyone,

I just exported my WordPress.com blog & plan on moving it over to my recently purchased GoDaddy hosted “www.remarpro.com” site. I installed Filezilla & can see these folders/files already installed by GoDaddy:

Folders:
cgi (empty)
php_uploads (empty)
stats (contains a “logs” folder (empty), & 3 files: .htaccess, .statspwd, index.html)

Files:
favicon.ico
gdform.php
missing.html
php.ini
welcome/html

I noticed there is a lot more files in the WordPress 2.9.2 folder I unzipped onto my desktop. Are these default GoDaddy files meant to stay, or should I delete them & upload everything from my WordPress 2.9.2 folder, or do I leave them alone & just upload the 2.9.2 files?
