hey one more question. so is every app that i see with ps -ef and not in the opt directory on root? or how do i read this.

i opened for example battery-eye and did the script its in usr/bin/ (is that the root?

Sorry for being so noob...

Not sure what you're trying to do here. "ps -ef" shows the currently running apps, and it's not necessarily straightforward to see which are in rootfs and which aren't (some use symlinks so they "appear" to be in the rootfs).

The easiest way of seeing which applications are on the rootfs is to use StorageUsage (unfortunately, still in extras-devel) - this flags in red those apps using significant rootfs space (it's currently inaccurate on python apps though).

Alternately the scripts I posted here can be used to show all apps using rootfs space, or to query the usage of individual apps.

As for battery-eye, that's optified (in /opt/battery-eye) - what's running from /usr/bin there is the python interpreter, which is in the rootfs (though most of the libraries it uses aren't) and probably ought to remain there for performance reasons.

sorry i meant desmume is in that directory. i will install disk usage. it sounds like a usefull program! thanks for all the help everyone!

you have multiple ways to fix the problem. I've given you already a hint. this goes to principal level: I'm not going to type "repartition" to the search textbox and click go -button and copypaste the second item in the list to here.... so go ahead and do it yourself..

I know about "repartition", thank you. But I dont think that it is right solution. However I wait some kind of resonance about idea of cloning Fremantle on SD.
