How to filter the Files from SharePoint Document Library based upon cloumn value

Question

Hi
I should filter the files from document library. I have column called "Print Status" for the document library the value would be either "Yes" or "No".
Now i should filter out the files which has "Print Status" as a "Yes".
I am using SPFolder and SPFile from SharePoint Object Model to traverse the file in doc library.
How could i do it?
My Sample code:
foreach (SPFolder childFolder in folder.SubFolders)
  if (childFolder.Name != "Forms")
    AspControls.TreeNode trn = new System.Web.UI.WebControls.TreeNode(childFolder.Name, "", "~/_layouts/images/itdl.gif", childFolder.ServerRelativeUrl.ToString(), "");
    newNode = TraverseFiles(childFolder, trn);
                            // add the new node to the tree
                            rootNode.ChildNodes.Add(newNode);
                    // loop through the files
                    foreach (SPFile childFile in folder.Files)
                        // create a new node and add to the tree
                        AspControls.TreeNode childNode = new System.Web.UI.WebControls.TreeNode(childFile.Name + " (" + childFile.TimeLastModified.ToShortDateString()
+ ")", Convert.ToString(childFile.Item["ID"]), "~/_layouts/images/" + childFile.IconUrl, childFile.ServerRelativeUrl.ToString(), "");
                        rootNode.ChildNodes.Add(childNode);

Why do you transvers the file an not use a camp query? In a CAML query you can filter the print status and are able to get all files and folder objects at once.
