SELECT contenttype, count(*) FROM content c GROUP BY c.contenttype

SELECT contenttype, count(*) FROM content c WHERE c.prevver is null GROUP BY c.contenttype

@page {
   @bottom-right {
    content: counter(page) " of " counter(pages);
   }

function menuItem() {
var folder = 
DriveApp.getFoldersByName('Test').next();
var contents = folder.searchFiles('title contains ".PDF"');
var file;
var name;
var sheet = SpreadsheetApp.getActiveSheet();
var count;

sheet.clear();
sheet.appendRow(["Name", "Number of pages"]);

while(contents.hasNext()) {
file = contents.next();
name = file.getName();
count = 
file.getBlob().getDataAsString().split("/Contents").length - 1;

data = [name, count]
sheet.appendRow(data);
