Merging a large number of PDF documents into one

Question

I am merging a large number of PDFs into one - possibly up to 10000 files. Each file is up to 6 pages long. My initial approach was to build a string array with as many elements as have file names and pass it to the Merge method. However, I am afraid that this way would overload the memory (this merge functionality is running as a service inside BizTalk) plus it could crash due to any one file having a problem, and would not know which.

Is it safer/more memory-efficient to merge files one by one, always adding a single file to an ever-growing file that is a result of previous merges?

Is it by any chance more memory-efficient to use ImportPage or Pages.Insert?

Thanks!

Hi,Thank you for your interest in Syncfusion products.It is more efficient to use Merge method that Import Page or Pages.Insert. However, we will check with our development team regarding the merging one by one or merging all the files.Regards,Geetha
