Asus Router Programming

[Marabunta]

I have an asus router and I want to delete a log file on my hdd which the download master is creating.
My HDD is directly connected to the router, so I have an config.json and I thought i could add sth. to make it delete the log file himself.

The problem is I have no idea of json and thats why I am here.
So if you could write me some lines to delete a folder every few seconds or know how to stop him creating(didnt find out where the creation code is to delete it) I would be very happy.

Thanks in advance

[rnd me]

can you make the log file have readonly/system attribs? this might prevent a write.
