body: <p>I have a json object as below:</p>

        {

          "documentTitle": "id.txt",
          "fileSize": 3894,
          "remarks": test1        
        },
        {
          "applicationDocumentId": 0,
          "documentTitle": "id.txt",
          "fileSize": 3894,
          "remarks": test2      
        }
      ] 
  </code></pre>
  
  <p>and 2 files with same name and size file (as id.txt above), but content is difference . </p>

  <p>when click save button, the files is uploaded on server and insert db, but I don't know exactly the which the remark match with which file. Please give me advise How to know the remark parameter in which file ?</p>
  
  <p>Using postman: entity is json object, files are the uploaded file
