Default Move large apps to SD CARD?

So I've recently rooted my NII and I feel like the internal memory has greatly reduced in size since. So in recovery mode I can see that the initial ROM and gapps that I flashed installed on the internal memory two extra times each but I can only see these extra/unnecessary files there and not an application such as Root Browser or Astro so I can delete them?

Also I was wondering if there might be a special app or ROM that would allow me to move large files/apps to my SD card?

Thanks
