Create a new share

When you create a new share, plan ahead.

On the Shares tab select Add Share.
Enter a name for your share in Share name

Share names
The Linux file systems used by Unraid are case sensitive while the SMB share system - the one used by Windows - is not. However, at the network level, case is ignored so media, Media, and MEDIA would all be the same share. When you view the share on the network, you only get the content of one of those underlying folders to appear - and it would not be clear which one this would be.
(Optional) Enter a description for the share in the Comments field. This is visible when viewed over the network.
Set a Minimum free space value, in kilobytes, if you plan to use the setting, otherwise leave it empty.
Select the Primary storage for your share. The dropdown displays all available options, which include: the cache, the array, and any named pool.
Select the Allocation method: high-water, fill-up, or most-free, depending on your use case. You can read about the differences here.
Select the Split level method for your data. You can find more information split level, here.
In Included disks choose which disks will be available to the share. By default, all disks will be included.
In Excluded disks choose which disks will not be available to the share. Note that if you configure Included disks there is no need to configure Excluded disks.
Select a Secondary storage if you plan on using it. Think of secondary storage as a fall-back resource when the primary storage is full. By default this is set to None.
(Optional) If you configure a primary and secondary storage, then Mover action option becomes active. This sets the direction of file transfers between Primary and Secondary storage.
Select Add share to complete the creation.

Note that, by default, a new share will not be shared over the network. You must configure network access after the share is created.
