WDsmartware building etilqs_ files in my windows temp folder - filling my drive!

Question: Wouldn’t it make sense to move these files to a location that Windows Disk Cleanup can remove? \windows\temp is not cleared by Disk Cleanup (at least not on XP it doesn’t appear to be). Perhaps one of the “Documents and settings… Local Settings…Temp” related locations would be better?

(Of course, I still prefer if the application could just remove the files it creates)
