Brief Intro:

The Drop Off Library is created when you activate the Content Organizer feature.  As soon as you configure the Content Organizer to start routing documents (which, actually it does when you activate the feature), all uploads to the site are automatically sent to the Drop Off Library.  It is just a typical SharePoint document library with a timer job that will process outstanding items.  Whenever you create a rule and select a content type, the Content Organizer checks to see if that content type has been added to the Drop Off Library yet.  If it hasn’t, the type is added to the library so that when the edit form is displayed after an item has been uploaded, users can select any one of the content types that are used in the routing rules.

A standard document library was used because it allows one to take advantage of all the typical document library features, such as:

• Workflow – users can start workflows on items in the Drop Off Library to approve a document, for example, before it is routed
• Content Approval – items can be forced through a content approval process prior to it being routed
• Check In / Check Out – allows items to stay in the Drop Off Library until all required properties for the content type have been filled out.  Once the properties are all completed though, items are routed whether or not they are checked in.
• Alerts – get notified when a new item is added to the Drop Off Library
• Permissions – create custom permissions for the drop off library.  If you have set the Redirect Users to the Drop Off Library property in the Content Organizer settings, then this allows you to effectively control who can upload content in the entire site, since all uploads get routed to the Drop Off Library

Configure Drop-off Library in SharePoint 2010 :

Before understand utilize Drop-Off Library also be look forward on Content Organizer Feature in SharePoint 2010.

What is Content Organizer??

The Content Organizer feature is a new routing feature that extends, enhances, and makes more broadly available the routing engine used in the Records Center site template from SharePoint 2007.  It not only allows you to automatically route documents to different libraries and folders within those libraries, it can also be used for mundane housekeeping type activities such as making sure that no folder within a document library contains more than 5000 items, for example.  When item number 5001 is added to the library, the Content Organizer can automatically create a new folder and put the document in that folder.  All of this routing and folder creation can be handled automatically without further user intervention.  After a document is uploaded and the required metadata applied, the upload form displays a Url to a document that has been routed so the user knows where to find it in the future.

Unfortunately the Content Organizer will only work on content types that are or derive from the Document content type.  So it does not work for automatically organizing large lists.

 Activated Content Organizer

There is one feature Content Organizer exists on Scope Web Features Collection SharePoint Site.

Feature should be on http://www.contoso.com/_layouts/ManageFeatures.aspx. Activate It.

After you activate the feature there are two new menus added to the Site Administration section(http://www.contoso.com/_layouts/settings.aspx) of your site settings:  Content Organizer Settings and Content Organizer Rules.

Content Organizer Settings :  Content Organizer Settings is where you configure whether to route documents that are added to the site collection based on rules.  Any changes made here affect routing for the entire site.

Content Organizer Rules:   Content Organizer Rules is where you go to create the rules that are used when routing documents.  Any rules created here are used to route individual documents based on metadata attributes that you choose.

In addition, there is also a document library that is created when the feature is activated, called the Drop Off Library.  It is:

• A library that users or custom code can use to submit new items that need to be routed
• Where all uploads may be temporarily routed if so configured in the Content Organizer settings (more info on that below)
• A temporary staging area for items that do not have all required metadata.  For example, when multiple items are uploaded to a document library they will go into the Drop Off Library by default, in a state where they are waiting to be checked in.  You need to edit the properties on the item, fill out any required properties and submit the changes in order to have the routing rules applied.

 Utility of Drop-Off-Library :

First create one new Content organizer rule that check document title. And if Document title and our defined title on our Content Organizer rule both are same than executed our Rule and Copy or Move Document to Destination Path.

Make sure we have created “Send to Connection” in Central Administration:

Go to Central Administration > General Administration Settings > Configure send to connection.

Add new Connection.

There are three options on Sent to Action. I have select move action. On that document move to destination path. If you select copy action than copy document to destination path.

What is Send to URL?

That is SharePoint OOTB web service url which you can find it out from content organizer setting on your site.

Create Content Organizer Rule:

Go to site setting > Site Administration > Content Organizer rules > Add new Item

Set proper name of your content Organizer rule. I have used DropTest.

I have set Conditions. On that when Document title will be “DocTest” than move to destination path which we have declared on path.

My Destination path is DropOffDocs.

Than Okay…

Using Programmatically Create Content Organizer Rule :

 using (SPSite osite = new SPSite(SPContext.Current.Web.Url))
            {
                using (SPWeb oweb = osite.OpenWeb())
                {
                    oweb.AllowUnsafeUpdates = true;

                    //We must get the EcmDocumentRoutingWeb object that corresponds to the current SPWeb
                    EcmDocumentRoutingWeb routingWeb = new EcmDocumentRoutingWeb(oweb);

                    //Get handles on the Document content type and the Shared Documents list
                    SPContentType contentTypeForRule = oweb.ContentTypes["Document"];
                    //SPList listForRule = currentWeb.Lists["Shared Documents"];

                    SPListItem listItem = listforRule.GetItemById(Itemid);

                    if (listItem.Folder != null)
                    {

                        //Create a rule object
                        EcmDocumentRouterRule newRule = new EcmDocumentRouterRule(oweb);

                        //Set the properties
                        newRule.Name = listItem.Folder.Name;
                        newRule.Description = "";
                        newRule.ContentTypeString = contentTypeForRule.Name;
                        newRule.RouteToExternalLocation = false;
                        newRule.ConditionsString = string.Format("", txtEmail.Text);
                        newRule.Priority = "5";
                        newRule.TargetPath = listItem.Folder.ServerRelativeUrl;

                        //Commit your changes
                        newRule.Update();

                    }

                }
            }

Upload Document to Drop off Library

Go to Drop off library > add new Document > title should be DocTitle.

Now see on your destination path location. Here is I have set destination path Shared Documents > DropOffDocs(Folder). So document automatically moves on that location.

That’s it!!!!!!!
