One folder in the Event Library is empty! Why?

Question

I recently uploaded many clips to iMovie '11. In the Event Library there are many folders. The problem is, one of those folders (selected in the screen shot) has no video clips in the corresponding Event Browser. +"The message in the Event Browser says: No video clips match the current selection. Choose a different option from the Show pop-up menu, below."+
What might I have done to cause that? I doubt that I actually selected all of the clips and deleted them!!

Hi Sundhar,
According to your description, you might want to check the existence of sub folder in a folder of a library using Client Object Model.
Please take the code demo below for a try, it will check whether there is sub folder in a given folder:
public static void createSubFolder(string siteUrl, string libName, string folderServerRelativeUrl)
ClientContext clientContext = new ClientContext(siteUrl);
List list = clientContext.Web.Lists.GetByTitle(libName);
CamlQuery camlQuery = new CamlQuery();
camlQuery.ViewXml =
@"<View Scope='RecursiveAll'>
<Query>
<Where>
<Eq>
<FieldRef Name='FSObjType' />
<Value Type='Integer'>1</Value>
</Eq>
</Where>
</Query>
</View>";
//camlQuery.FolderServerRelativeUrl = "/Lib1/folder1";
camlQuery.FolderServerRelativeUrl = folderServerRelativeUrl;
ListItemCollection items = list.GetItems(camlQuery);
clientContext.Load(items);
clientContext.ExecuteQuery();
Console.WriteLine(items.Count);
if (0 == items.Count)
//create sub folder here
