any reason you can't store as regular text and format it as a hyperlink?

Where Me!Document = ResourceDocs#C:\LinkedDocuments\ResourceDocs#, this will
open Windows Explorer properly and display the contents of the ResourceDocs
folder:

   strSysRoot = Environ("SystemRoot")
   strExplorer = strSysRoot & "\explorer.exe"
   strExplorer = strExplorer & " " & HyperlinkPart(Me!Document, acAddress)
   Call Shell(strExplorer, vbHide)

Why use a Hyperlink to open the file? Why not just store the path and
filename and then open the file using the following:
Dim RetVal As Variant
   Dim stFile As String
   stFile = DLookup("[DataPath]", "tblApplicationInfo") & "CutSheets\"
& Me!FileName
   RetVal = fHandleFile(stFile, WIN_NORMAL)

Note that I only store the file name in the field, and use a reference
to where the files are located in a table called tblApplicationInfo
where I store information about the application.
In this example, the file (an Excel file in this application) is stored
in a subfolder of the folder listed in the DataPath field so it is
added to the string in the appropriate location. The Me!FileName refers
to the name of the file on the form.
This code will open any file you tell it to, as long as the
corresponding application is installed on your computer (example: Word
must be installed to open a Word Document, or a paint or image editing
application to open a JPG file, etc.).
