Structure of a Workflow

There are some basic rules that workflows have to follow.

"Workflows" are folders inside the workflow root folder.
The main configuration file for each workflow is _wfconfig.ps1. This name cannot be changed.
Some data is stored in the sub folder _wfdata. Ths name cannot be changed. It is not important to keep this folder. Everything in it can get lost. It contains "last run" timestamps and a serialized version of _wfconfig.ps1.
The workflow folder contains a workflow script. It's name can be configured in the _wfconfig.ps1.
In case of "state machine workflows" there can be one or more workflow state scripts. All of them start with "S_", but the name can be configured in _wfconfig.ps1.
For SharePoint workflows you can have a "pre query" script in the workflow folder. It's usage and name is configured in _wfconfig.ps1.
For all workflows except "PowerShell" workflows you can have a separate "error handling" script that is executed in case of unhandled errors. It's usage an name is configured in _wfconfig.ps1.
When using the kenaflow embedded workflow templates you will have these files additionally. They can be removed.

.gitignore
_initialize.bat : This is a shortcut to the next file...
_initialize.ps1 : This can be used to create workflow lists, the workflow state field (in case of "state machine" workflows) and the kenaflow defined permission sets.
