Storing pdfs in access database Through C#

Question

Hi, I am a new programmer and am trying to develop a software that will enable storing of old documents from a large company as pdfs in a access database as well as 3 other key fields that will enable to search through the database for each document. Through my research I found that it is possible to store the pdf directly to access as a OLE binary file and i have managed to store it into the database but I am unable to reverse the process to retrieve and open the pdf document. Is it better to store the pdf in a folder and store a pointer to the document into the database and if so how do you store the path pointer into the access database from a Windows form using Visual C#. Thank you for your attention
