input type file limit size

// With Jquery 
$("#aFile_upload").on("change", function (e) {

    var count=1;
    var files = e.currentTarget.files; // puts all files into an array

    // call them as such; files[0].size will get you the file size of the 0th file
    for (var x in files) {

        var filesize = ((files[x].size/1024)/1024).toFixed(4); // MB

        if (files[x].name != "item" && typeof files[x].name != "undefined" && filesize <= 10) { 

            if (count > 1) {

                approvedHTML += ", "+files[x].name;
