[NTG-context] How to ged rid of temporary files, forever?

Hi, I have a folder where I store my tex sources and generated pdfs. The problem is that now it is overflooded with temporary files (top, tuo,log,...). I remember Hans wrote somewhere that LuaTeX will hold temporary files in memory... But they are still there, on the disk. Yes, I know the --purge-all option, but it is too long to write "context filename --purge-all ", isn't it? It would be very nice if we could set an option somewhere (for example, in the registry) to NOT generate temporary files, and even log files (I never use them). Best regards, Vyatcheslav Yastkovsky
