old stuff 3 - change your opera cache folder (Symbian S60v5)

edit opera.ini, and add the following line under [User Prefs] section:

eg: this will chg the cache dir to e:\cache\opera
Cache Directory4=e:\\Cache\\Opera\\

remember to use double slash

old stuff 2 - minimized silent/muted wav/mp3/mp4/aac files

sometimes, certain sound files are treated as system files and cannot be removed. although you don like them or they consume too many disk space, you cannot delete them.

so i made these silent sound files and kept minized in size. they are playable and thus can be recognized, and were trimmed to 0 or 1 sec long with very low bitrate.

empty.aac.7z

empty.mp3.7z

empty.mp4.7z

empty.wav.7z

old stuff 1 - reclaim 8Mb in core! (Symbian S60v5)

reclaimed 8M space (yes, more than 8MB) by removing build-in game bounce and raging thunder (you can remove others also if not needed inside core)

some system files cannot be deleted even you don need them. however, some of them checked by the system for existence only, so this trick is to replace these files with empty files

howto:
(bounce, for example)
create these empty files and save them in rofs3
\sys\bin\Bounce.exe
\resource\apps\Bounce.rsc
\resource\apps\Bounce_aif.mif
\private\10003a3f\import\apps\Bounce_reg.rsc

and finally, the trick is ....
create an empty file in private and named it 2000C4D4 (it's \private\2000C4D4 that occupy 8MB)
YES!! an empty file is enough to prevent the 2000C4D4 directory inside core being copied to Z!! (due to the priority rule for building)
DONE!!
