Yes it's possible. You can do it with Ajax and FormData API:

var file = s.fileInputEl.dom.files[0],
     data = new FormData();
data.append('file', file);
Ext.Ajax.request({
   url: '/upload/files',
   rawData: data,
   headers: {'Content-Type':null}, //to use content type of FormData
   success: function(response){
   }
});

See online demo here

 Use 'filefield' control of Extjs 4. and check below links

I didn't check the same but i think it should help.
