I am using uwc (3.13.0) for converting our DokuWiki (Release 2010-11-07a "Anteater") using the hierarchy conversion.
I have copied the wiki to external local harddisk so I have the folders
E:\DevelopWiki\data\pages\Develop\Teams
E:\DevelopWiki\data\media\Develop\Teams
Each of those contains multiple subfolders (one per team)
So when converting I put the follow in the GUI of UWC:
Attachments: E:\DevelopWiki\data\media\Develop\Teams\TeamWebBE
Pages: E:\DevelopWiki\data\pages\Develop\Teams\TeamWebBE
In the config file there are the following settings:
DokuWiki.001.space-TeamMacGyver.property =TeamWebBE
DokuWiki.001.attachmentdirectory.property=E:/DevelopWiki/data/media/Develop/Teams/TeamWebBE
The pages and the hierarchy import well, but the attachments are not imported
So the wiki markup contains correctly built strings like "<ri:attachment ri:filename="teamlogo.jpg">" but there are no attachments anywhere in the space.
