SPServices Add New Folder in library and also subfolders.

For New Folder:

var librarynaem = "";

var newfolder = "foldername";

function CreateFolder() {

jQuery().SPServices({

operation: "UpdateListItems",

async: false,

listName: librarynaem ,

updates: "<Batch OnError='Continue' PreCalc='TRUE' ListVersion='0' >" +

"<Method ID='1' Cmd='New'>" +

"<Field Name='FSObjType'>1</Field>" +

"<Field Name='BaseName'>" + newfolder + "</Field>" +

"</Method>" +

"</Batch>",

completefunc: function(xData, Status) {

//alert("Status=" + Status);

}

});

}

To dd sub folders pass the folder location:

as newfolder ="folder1/folder2/yourfoldername";
