likely best that I try to convey folder structure:

"client type"  (wholesale or retail)

     "client"     (john doe, harry james, yosemite sam, ...)

              "annual work"

                        "year"    (2013, 2014, 2015, ...)

                                   "data received"  (where we would save the download)

ok.... so a few things about importing docs into LF  First you have to create the placeholder.  Kind of like a "shell" that the document will occupy, then you have to place the file in the "shell"

so the steps:

1. Establish the connection

LFApplication lfApp = new LFApplication();

LFServer lfServ = (LFServer)lfApp.GetServerByName("LF Server Name");

lfRepository = (LFDatabase)lfServ.GetDatabaseByName(Repository);

lfCon = new LFConnection();

lfCon.UserName = username;

lfCon.Password = password;

lfCon.Create(lfRepository);

2. instantiate your objects

LFDocument newDoc = new LFDocument();

LFVolume lfVol = (LFVolume)lfRepository.GetVolumeByName(Volumne name)

LFFolder folder = (LFFolder)lfRepository.GetEntryByGUID(folderGUIID);  there are a few methods to get the folder.  this is the one I use in my app because the folders are generated dynamically and it is just easier for me. You can also GetEntryByPath and don't remember any others off hand

3. Create the "shell" I mentioned before (the third parameter in newDoc.Create is for auto rename incase the doc already exists with same name in the folder)

newDoc.Create(document name as it will be in LF, LF Folder from step 2, LF Volume from Step 2, false); // Create place holder for the Document. No actual information is stored in the document

LFAccessRights rights = (LFAccessRights)newDoc.Rights;

rights.InheritsRights = true;  //New Document inherits the access rights from the parent folder

newDoc.Dispose(); //Clean up

4.  This part actually inserts your PDF into the shell created above

DocumentImporter docImporter = new DocumentImporter(); //This actually imports the data into the placeholder created for the document

LFDocument doc = (LFDocument)lfRepository.GetEntryByNameAndParent(document name as it will be in LF, LF Folder from step 2);

docImporter.Document = doc;

docImporter.ImportElectronicFile(This is the FULL PATH to the document);

doc.Dispose(); //Clean up
