OK when I do a dump, this is what I do...
Cut all the results files from the pcs into the same folder, results1, results2...etc
Make a copy of the folder, incase something gets lost.
Run muon monitor, run merge results files, select the results, and merge them.
The original results1...etc stays in the folder.
The merged results file is saved to c:\prog files\muon1\mergeresults.txt...you can change it if you like.
Then just rename to results.txt and send.
You don't have to stop muon, if you created the new results file and wait a while before you send it, muon will just add it's new results to it.
Hope this helps! 😉
