Hi,
I looked at this folder also. Looks like some sort of backup of the jobs.xml
In my folder I had 2 extra jobs.xxxxx.xxx.xml files, but after a while one was gone. I still have one from 4 months ago..
Looks like some internal process of Visualcron is doing this as this is its own settings folder.
I renamed the last one (added a '_' in front) just to see what will happen, for now, it looks all good.
Just don't delete the jobs.xml file!
Regards,
Erik
