It seems like this is broken in 5.0.1 but I have been able to get it working by manually doing the following:
1. Make sure you log in as the DNN host or super user (not just the portal admin).
2. Find out what the ModuleID is for your DMX module - a simple way to do this is open the Settings for the module and the ModuleID will be in the URL of the page, for example, on my site, the URL I see is (note that FolderAdministration in my URL is because my page is named Folder Administration, yours will be something different)
http://yourdomain/dnn1/Fo...eId/399/Default.aspx
The ModuleID is the number after ModuleId in the path, so mine is 399
3. Open the page with the DMX and right-click the folder you want to import into, click Navigate.
You should see the page displayed again, but the URL in your browser will now be showing the EntryId of the folder, which is the next thing we need, something like
http://yourdomain/dnn1/Fo...t.aspx?EntryId=10303
4. Edit the URL by replacing "EntryId" with "ctl=Import&mid=399&CollectionId" - don't type the quotes and replace 399 with your ModuleId, so the URL should now be something like
http://yourdomain/dnn1/Fo...p;CollectionId=10303
5. Press Enter to navigate to the modified URL and you should see the Import form.
6. You now need to type the local path on the server to the folder where you want to import from in the Directory text box. If the files you want to import are on your computer, you must first upload them to the server with FTP or however you get files to your server. The path must be accessible to the account that your web site runs under on the server - if you're using a public server, this may need to be a folder below the web site root. The files will be copied during import to the DMX root folder.
7. Click Test access. If you have the path right and the web site account has access, you'll see a message that says "I can successfully read " and the Import button will be enabled.
8. Click Import and watch all your files and folders being imported!
NOTE: I have found that the import works very well except for one catch - make sure none of your file names start with a tilde (~), some apps create temporary files with a tilde at the beginning of the name, and I have found that stops the import with an error. It's not a huge deal, just delete the offending file and start again, but if you can get rid of any files like that before you start you shouldn't have any problems.
From what I can tell the import has been moved to the new menu I posted in a previous reply, but it's not working - Peter any timeframe for when Import will be fixed?
