Then for clarity for other users....
You only need share a remote folder with read/write access, using SAMBA or Windows sharing.
Ideally, this folder will be empty. When you tell LMCE to use the LMCE folder structure, during the detection wizard, LMCE will then create all the necessary folders you need automatically. You can then move your media into the appropriate folders and it will be scanned into the database.
If the share already has media in it, that is fine - LMCE will still create the folder structure, then you can just relocate the media from its current location, into these folders and it will be scanned into the database.
If the share already has a LMCE folder structure on it and perhaps some media in that folder structure, LMCE will recognise this and reuse that folder structure, then re-scan the media content of those folders back into the database.
