Upload files to Sharepoint document libraries via FTP
I don't think so. I think your options are:
- HTTP (via the upload page)
- WebDAV
- Web Services
- The object model
You can map a drive to a SharePoint document library, for example \\serveraddress.domain.com\Documents. So I would try mapping a drive on your FTP server, then making sure files that come in over FTP get sent to that drive.
Big edit: Have any of you figured out how to upload to SharePoint (WSS)? I've tried drive mapping and then using Robocopy and Synctoy to copy files thinking a tool might offer greater control (i.e. a Copy Date Modified control). As I understand it the files are actually stored in SharePoint as database objects and therefore SharePoint views display the database object (SQL object's) properties in Document Libraries where a new user would expect to see the file properties. Those file properties are still alive! They just need to be uncovered by a different view. I particularly like the mapped network drive view of a SharePoint Document Library. File attributes are pretty important to my team, so we were concerned about that at the start. As an opinion note though, the default view showing attributes that appear as incorrect is just plain annoying!
The best solution we've come up with for doing large file migrations into SharePoint is a mapped network drive then using a tool called FreeFileSync available at SourceForge to move your files and folders. It's great because it produces verbose error messages and give a lot of control, especially for the instances that SharePoint tries to block a particular filename or file extension.
