Using Subprocesses to share functionalities across Processes

Subprocesses are also useful when it is necessary to implement the same Task multiple times. An example of the use of a Subprocess can be in the situation where there is a need to implement a file transfer to and from different locations, but the Process also needs to be doing something else at the same time, meaning Subprocesses can be used to compensate for the short-handed Process.

It is most often more useful to separate the file transfer part of the Process into a Subprocess so if this part is needed in some other Process, it can use the Subprocess instead of creating a whole new Process for that.
