The Zip menu in RunDynam allows you to zip up (or restore) all results from a simulation. Occasionally users report intermittent errrors when doing this. They may get messages such as: "Invalid File: not a PKZip file".
Because the error is intermittent (ie, not repeatable) it is hard to track the cause. For large models with many time periods, the total size of all output files can be very large (several gigabytes). The zipping operation may be overloading computer resources! To avoid the problem, reduce the strain using one or more of the methods below:
Any combination of the above tactics will make the job easier, and reduce the frequency of these intermittent errors.
