/////// Problem Statement////////

Sir, we are using the Aspose Sample code for Extracting Attachment from pdf file. The attachment file successfully extracted but problem is that extracted file is in non-readable format( when we want to open Extracted Attachment file then it is showing an error:- " File format is not supported").
