POST file list to controller in ajax post

I tried to upload documents but I couldnt pass to list my controllers parameter. My scenario is:

  1. user click to "choose file" button and pick the files and press done
  2. then my some functions get file list and pass to controller for save locally via POST merhod like below:

view side: (get file list)

   function saveDocuments(documentList) {
        if (documentList.length > 0)
            var formList = new Array;
            for (var i = 0; i < documentList.length; i++) {
                var form = new FormData();
                var file = documentList[i];

                form.append('FormFile', file);

view side: (post file list)

 function savePhysicalFile(formData)
        if (formData != null)
                url: "Installation/SavePhysicalPath",
                type: 'POST',
                dataType: "json",
                contentType: "multipart/form-data",
                processData: false,
                contentType: false,
                success: function (result) {
                    console.log("Success", result);
                error: function (data) {

In my controller side; the parameter "model" is always null. I couldnt pass view side list here. How can I figure out ?

controller side

public JsonResult SavePhysicalPath([FromForm] List<FileModel> model)
            var savingRootPath = @"C:\MyDocuments";

            //I'm doing save locally
            return Json(savingRootPath);

model side

    public class FileModel
        public string Files { get; set; }

        public IFormFile FormFile { get; set; }
