after any freeze

require("Storage").eraseAll();

Removes all files, including apps that can't be removed from apps loader 

E.setTimeZone(2);

peek16(0x300c).toString(16);   //TO see the espruino SDK

//0x8C or 0x91 is SDK12

//0x81 or 0x88 is SDK11

Memory usage per app


print(require("Storage").list().map(f=>require("Storage").read(f).length.toString().padStart(7)+" - "+f).sort());

It'll list all files sorted by size and you can see what's taking up the space
