Right.. What you want to do can be done using the method I've given and in some cases, depending how how you wish to configure users, you may not even been to move a single file.
Login to the NAS's dashboard UI. I'l assume you've ot changed it's name from MyBookLiveDuo.
Go to web address: http://MyBookLiveDuo/UI/ssh
Enable SSH. Read the blurb that's on that page.
Download an SSH client. Don't lknow what to use on a Mac. If it's a PC the use PuTTY (Use Google to find it.)
Start an SSH session to the MyBookLive.
Login using the credentials shown on the web page http://MyBookLiveDuo/UI/ssh.
Once you have the Linux command prompt issue the following command.
Add the following lines to the top of the text file you'll be editing exactly as shown.
path = /shares
comment = Root of NAS's shares
browseable = yes
invalid users =
valid users = admin
read list =
write list = admin
map read only = no
You may change the word Root to whatever suits you.
Don't change the file name. Just press ENTER and if asked to overwrite the file, allow the overwrite.
Press CTRL/D to logout.
You now has access to all the other shares as defined on the Dashboard UI but represented as folders/directories.
If you wish to create and remove these directories from the new single share (does not appear on the Dashboard UI) then use the Dashboard board UI to do his otherwise under all the shares.
If this is not what you wish then create a new share under the Dashboad UI and use the other suggestion to move the files and folders from all the other shared into the blank share using the Linux
mv command or install Midnight Commander on the MBLD and use that.
Final option is the one that takes the longest and create the new share and use the computer to move everything betwen shares whicl will take a while because all the file data will be copied to your computer and then back to the MBLD. I'm not 100% sure how Total Commander will do this but I think it'll do the same as this third option does.
If you're moving files from one folder to another on tbe MBLD then Samba will just relocate the files and folders. This can't be done when moving between network shares even if it is on the same device.
Hope that helps.
