The component should also display a browse & upload in order for the user to upload the file , or update it. You can hard code amazon s3 storage credentials for the time being. When the file is uploaded the component should update it in the field Path_To_File__c using dynamic soql. NOTE: it is important that we use javascript library for amazon instead of the apex one since we want to be able to allow bigger files to be uploaded as well.
