jQuery multiple FileUpload Context.Request.Files.Count always Zero in ASP.Net

When i click the button all the files need to be zipped and save in a folder, i am getting the zip file when i save separately, but when i use generic handler it is always returning zero..so the code to save the files in folder is not working as required..

These are My functions Whenever i upload files , my generic handler  context.Request.Files.Count > 0 is always Zero,

<script type="text/javascript">
    function aspserver() {
        zippedFiles = zipFiles();
        console.log(zip.files);
        zippedFiles.generateAsync(zipOptions)
        .then(function (content) {
            aspupload(content)
            saveAs(content, "test.zip");
        });
    }

    function aspupload(zipContent) {
        console.log(zipContent);
        var fileObj = new File([zipContent], "test.zip");
        /* form data oject */
        var formData = new FormData();
        ///* $('#file')[0].files[0] */
        formData.append('file', fileObj);
        formData.append('fileName', "test.zip");
        $.ajax({
            url: "FileUploadHandler.ashx",
            type: "POST",
            data: zipContent,
            contentType: false,
            processData: false,
            success: function (result) { alert(result); },
            error: function (err) {
                alert(err.statusText)
            }
        });
    }
</script>

Generic handler to save Files in a Uploads folder, But Every time it is returning zero if i have files also...

public void ProcessRequest(HttpContext context)
{
    var cctype = context.Request.ContentLength;
    var uploadFileSize = context.Request.ContentLength;
    if (uploadFileSize > 1)
    {
        context.Response.Write("HttpPostedFile.ContentLength!");
        //return;
    }
    if (context.Request.Files.Count > 0) // always Zero..??
    {
        HttpFileCollection files = context.Request.Files;
        for (int i = 0; i < files.Count; i++)
        {
            HttpPostedFile file = files[i];
            string fname = context.Server.MapPath("~/uploads/" + file.FileName);
            file.SaveAs(fname);
        }
        context.Response.ContentType = "application/x-zip-compressed";
        context.Response.Write("file uploaded successfully!");
    }
}
