In SilkTest is there any way to retrieve results from the temporary files when a TestScript/TestPlan crashes before completion?
No. The temporary files are purely for the temporary storage of data until the test is completed and cannot be used to reconstruct a crashed test scenario. If you find your tests are constantly crashing and results are being lost, it is better to try to resolve the issue causing the crash rather than trying to find a way to tolerate the problem. There is no planned enhancement for the ability to retrieve results from the SilkTest temporary files.
