If you're in Workbench, then it's a little more complicated. In Autosave there's a "retain x previous cases" option. If you run in standalone you can overwrite/delete spare files as required. I do recommend saving all data locally as the solvers assume the disc/storage can write as quickly as data is dumped to them, if they can't you can lose packets and finish up with a corrupt file. That's less of an issue at present as USBs are much improved from 10 years ago but I expect it to more common again as the file write software improves faster than hardware.
