Some modules support copying of files via PS dataset. This method is much faster than copying members one by one. Files are stored in one big file and split to members on the other side. Because this method of copying requires a job submission then it is faster than the standard method only when a number of files is higher than a threshold (currently set to 5). Set actions for which you want to activate this method to true. Note that PS method is used only when the number of files equals at least the defined threshold.
In the example PS method is used for reading, exporting and importing files when at least 5 members are selected.
