PDF attachments size limit

I am trying to add attachment to existed PDF document:

                PdfLoadedDocument doc1 = new PdfLoadedDocument(tempFile);
                if (doc1.Attachments == null)

                PdfAttachment attachment = new PdfAttachment(attachmentPath);
                attachment.ModificationDate = DateTime.Now;
                attachment.Description = info.Name;
                attachment.MimeType = "application/txt";



It works fine for small attachments, but it gives "Exception of type 'System.OutOfMemoryException' was thrown." for 200Mb attachments.
Do you have any attachments size limit? How we can increase this size?

Hi Karthik,

Do you have any updates? It's hard to believe that I am first Synsfusion user who faced with pdf attachments file size limitation issue.
I double checked, I have OutOfMemoryException event with files more that 100 MB.   

Thank you.
