From your question and comments, it seems you are a novice at Access. Let me ask a more important question. Are you aware of the size limits in an Access database? Because loading scanned documents can rapidly blow past the size limits on Access back-end or stand-alone files.
Questions you should be asking at the preliminary phase include "What is the size of each file I am loading?" "How many files am I planning to load?" "What will I do with those files once I have them?" "Will I have to remove, replace, or otherwise interact with the loaded content at a detailed level?" "Will I need to read the files other than as images - i.e. text mods?"
Imported scanned files that are actually stored in the DB do not shrink in size. There are two approaches to loading scanned files. One is to walk into it knowing you will have limited numbers of files. The other is to move the files to a safe place on your target disk but only keep the file specification (device, path, name, type) in the DB and just reference it when you need it.
