does anyone here know how to hide the jaggexcache folder, jagexappletviewer file and jagex_cl_runescape_LIVE file from the home folder?

The problem is this, everytime you play runescape (in both windows or linux), it creates those files and folders. The problem is that on windows, you can hide them and everything is fine. On linux, if you add ( /.) to the folder or file to hide it, when you play runescape, those files and folders are again created, because they cannot be found.

As far as I know, the game is Java based (needs java iced tea plug in and java 7), so is there any way of changing the directory where the game puts all those files? like home/documents instead of just /home

thanks!
