Hi thanks for reply,
the pdf documents are not password protected but the Page Extraction feature is disabled which is wanted to split the file as shown above and this is running in server. Application is designed in c# so please tell me any kind of solution or possibilities will help to split. if there is no solution in C#, then also it is fine.
In Adobe Acrobat UI itself the pdf is disabled the extract method.
I believe there will be any techniques to resolve this.
Thanks
