Hi Doreen,
I don't think manually creating folders and then manually moving the XML files is a good idea. Users make mistakes, so it's best to control what they can and cannot do. As the form designer, you can control this with some simple changes. Basically, you would allow DBXL to control the SharePoint mapping, via a conditional mapping.
Your document type would have two SharePoint mappings, each with its own condition. For example
http://<myserver>/<myACTIVElibrary>
Condition: my:status = 'Active'
http://<myserver>/<myINACTIVElibrary>
Condition: my:status = 'Inactive'
Within the form, you would have a simple status field (Active vs. Inactive). Its value will then control whether the form is mapped to the Active library or the Inactive library.
The database mapping is not affected by any of this.
Hope this helps!
