apologies for being dumb; how do I boot recovery (CWM)?
EDIT: ok so JFGI: i rooted my phone using http://www.androidauthority.com/galaxy-s3-gt-i9300-root-clockworkmod-recovery-95849/
then booted into recovery following instructions:
Hold Press Volume Up +Home Button + Power Button (note: press this 3 button in the same time). Releases this 3 button when you get the Samsung Galaxy S3 Text Display on the screen. Now you will boot into CWM Recovery Mode.
then could only wipe 'dalvnic' cache (can't remember if dalvnic is sp right here)
so i wiped it...
then i bought root explorer from play store to find the folder in question...
and finally 90 minutes later... it worked... i can copy n paste again.
