I want that every day the data of my webform being :
1 - downloaded with the download function of the module (=>saved)
(it is only possible to do it manually or with different options as
"Submissions by number from /.../ and optionally to: "
"Submissions by date from /.../ and optionally to: " )
2 - and then erased (there is also a "Clear" function in the module)
I have tried to find solutions with Rules, Rules Scheduler, Job Scheduler, ...
auto-edit : I think the best way could be with cron, but I don't know how.
