Job files and custom Work directories
The Work directory is where job files related to the current project are stored and accessed on the computer where InfoSphere® MDM is running.
such as: C:\myhubinstance\inst\mpinet_myhubinstance\work\.
When a job is run from MDM Workbench, it always adds the projectname directory and, if you specify a "Work directory" in the New Job Set wizard, the ~workdir portion. Both the projectname and ~workdir values are passed to the operational server in the job set information submitted by MDM Workbench.
