50 -The first Type available to you is Volume. With this option, you create one or more folders on Docker relevant to that runtime to read and write **persistent** data. To configure this Type, you need to link the runtime volume to a machine volume (or network volume) you can create within the same pop-up. This means you can re-use a "Machine volume" or a "Network volume" over multiple runtimes (i.e., containers). To do so we first need to define a machine (or network) volume. Once we have done that we can learn how to link the volume to the machine or network volume.

This target defines the second part of the path to which the runtime will gain access. For example, when you fill in "/target", we can combine this with the "Volume" name to arrive at the correct directory from which eMagiz needs to read data (or write data to). So in our case in which we link the volume to the machine volume we created earlier, this would be "/file-directory/target."

86 -An alternative option to read and write **persistent** data is to use the "Bind mount" option.
