Link Directories On MULTIPLE DRIVES To A Single Folder

Is there any way to link directories on several DIFFERENT HDD's to the SAME top directory / library.

Trying a Multi-media server with video files on HDD1, HDD2, HDD3.

What I want is to say create a top level directory videos, then under that directories video1, video2 and video3,so my application which says Multi-media folder -- I could point to directory videos -- then I'd get the 3 folders as part of the top level directory.

(Using Spanned disks can work but I'd rather not go down that route these days as the 3 disks I want to use are EXTERNAL HDD's and spanned disks need ALL the drives to be available and if there's any error you lose THE LOT. !!! )

With Linux it's easy -- just create 4 directories in your /home folder say /mnt/videos as top level, then in this directory create 3 sub directories /mnt/videos1, /mnt/videos2, mnt/videos 3

then mount the devices /dev/sdb1, /dev/sdb2, /devsdb3 in /mnt/videos1, mnt/videos2, mnt/videos3

then browsing your home directory with mnt/videos you'll see all the data files in the 3 directories from all 3 HDD's -- no matter what their size, -- you only need a FEW BYTES too in your home directory !!. You don't actually copy or move any data from the HDD's to these directories. Things like search are great too since you point the search at the top level directory and the system will scan all the sub directories (so all 3 disks) too.

A lot of multi-media type programs seem only to handle ONE top level folder so when the HDD is full you are stuffed -- maybe limitations of the windows file system. I've seen somewhere that you can use some type of links if you have multiple devices but can't find it.

How does a NAS device handle multiple HDD's within the server.

The old library feature was half way there but in Windows 8.1 that feature seems to have GONE.
