wich services has this funcionality?

thx 4u help

Do you mean a folder in the file system on disk, or a folder in the MWS taxonomy? If the former, than please see this post: It has an attachment: HowToUploadDownloadFiles.doc

If the latter, then you’ll need to use the PortalContainerAttachmentsProvider and specify a valid containerID (either an alias or a folder id).
