Sharepoint 2010: Copy or add file to Document Library

I have a silverlight application inserted in a SharePoint page. The SilverLight application runs on a different server thatn that of SharePoint. From an event in the S开发者_如何学GoilverLight, I generate a document on the server side from SQL Server. I can generate the doc on the server hosting the silverlight application and also copy it to the SharePoint server. I wanted to know if I can include this file in a sharepoint document library automatically. I was thinking if like emailing to a list allows us to copy the file into the library, can we configure the reverse, means copying the file make it part of the list.

Update:

I wanted to avoid uploading. For me uploading is sending the file from one location to the target location. But what I am saying is, if I copy the file into the folder where SharePoint keeps the file physically for the particular list, can it be added to the list automatically?

I am not sure, how well I am being able to describe the point. Please elaborate if required or I can answer your queries.

SharePoint stores the files in a database, not a folder.

WebDAV access may be what you're looking for - it's a backbone of the the Explorer View feature that allows a user to access a document library as if you were accessing a file system through a Windows Explorer window.

You can configure "incoming e-mail" properties for the document library, and assign an e-mail address.

After that, when you e-mail a document as attached to e-mail to this e-mail address, then attachment will be saved to that library by sharepoint automatically.
