Insert Object only from a specific folder

[motleyjew]

Currently I have a table called documents with about 10 ole objects. The fields are doc1, doc2, doc3,.....etc. I have set up a form with 10 bound Object Frames and a command button for each ole object. I put VBA code in the on click event that says:
Me.doc1.SetFocus
DoCmd.RunCommand acCmdInsertObject
I have the OLE object set to used Linked. This is all working great, however, I need to find a way for the users to only have the option to get documents from one particular folder on our network. The current setting gives me the choice to browse multiple folders. We want to be able to make this particular folder read only so no one is able to delete these documents. Any suggestions would be great. I tried searching the forum, but have not had any luck.

Thanks
Gregg
