Merging PDF

[FeliceR]

I'm trying to append 900 PDF files for creating an unique PDF file.
The operation is OK, but all the PDFs all loaded in memory.
The code for the operation is:

Dim paths() As String = Directory.GetFiles("c:\tmp\testpdf\949pdf")

Dim pdf As PdfDocument = PdfDocument.Merge(paths)

pdf.Save("c:\tmp\testpdf\totale.pdf")
pdf.Close(True)

The memory increases a lot.
Is there a way for avoid loading all PDF files in memory? ...or for flushing memory?

Thank you for your interest in Essential Studio.
