Thank you for your post.
Since all the files are loaded in the Documents folder, you can use the function Get(DocumentsPathListing) to list all the files in the Documents path. For example, create a table with one text field, FILES, and create a script with the following steps:
Go to Layout [ <layout with FILES field> ]
Set Field [ FILES ; Get ( DocumentPathListing ) ]
You can then parse this out and populate another table with the file names.
Let me know if you need additional clarificaton.
