Archived Results are raw file system archives for each node and can be downloaded at the completion of a flood load test by clicking on the gear icon and selecting Archived Results.
This will give you a link to each grid node's results which can be retrieved up to 30 days from the flood's completion.
Download the compressed archive and unzip it to find a folder called
flood. Within that folder, you'll find:
filesfolder, in which you can find the script and other data files that you uploaded to Flood before execution
flood.logfile, which is a record of the execution of the test
grid.logfile, which is a print-out of the contents of the console on the grid node
resultsfolder, which for JMeter contains the file
results.csv, in which the raw transaction details are recorded
screenshots folder for Element tests, which contains the screenshots from the test depending on the configuration of the script
