How do i upload files for a hosted website

If that means that your ASP.NET web-site is not hosted on that server in US then you can IDEALLY ask the server administrator for FTP access credentials.

Then from you ASP.NET web-site you can use FTP protocal to post your files on that server in US.

I have the credentials, but the users of the website will be required to upload and download files regularly

Anthony,
     There are several methods of uploading files to a hosting server.  It really depends on who's hosting it and what they allow.

For Example:
     Host via ISP: Typically all you need is an FTP application to make the connection and upload the files (FileZilla works nice for me), the URL of the hosting location, (websites.ISP.com/MyAccountName) and the account information to access the site (Username, Password).  I know Charter Communications has a setup method on their website, One of our local companies provides the customer with the account information, etc... it just depends on who's hosting as to the specific method used.
     Hosting via Web Publishing Specific Companies: I know the Blue Voda company requires you use their servers and will provide you with an account (for a fee of course).  All you would need to do is use their account information and select the appropriate server from within their publishing application to upload the site.

     If this hasn't helped your situation, please provide more information (The Hosting Company Name would be helpful) and one of the experts here, or myself will be able to provide further assistance.

Thanks Lupinus

I am using winhost.com to host the website. This website will be used by about 70 persons scattered around the world. One of their goal is to share documents by they themselves uploading say ms-word or pdf documents to the site such that members in the group can download are use them

Thanks Anthony
