Sorry I didn't get back to this thread until now. Yes, The files that are taking so much space is your nandroid. the new cwm stores the backup in two separate folders clockworkmod / backup you will find backups. in clockworkmod / blobs you will find backup data.
The way I understand the blob folder contains all the data for all of your nandroids. When you have more than one backup and they have common files such as apk's they share them. In the long run, if you have multiple backups it saves space. Roms from touchwiz roms can easily reach a gb. When you delete a backup you also need to delete the unused backup data. To do this, boot into recovery and go to "backup and restore. Then choose free unused backup data. This will delete all backup data that is no longer being used by a current backup... I hope this helps you understand.
Yup, that was it, thank you very much I got my space back
So all I do for the past 3 hours was run in a circle, lmao, ah well, i learned some new stuff from you guys in the process
So thanks for all the help
So all in all, it had worked I guess? Right?
So now that I've deleted it I need to create the backup again. And then download the rom online, put it on my sd card then go into recovery mode and install it?
On my Samsung galaxy s3 running android 4.0
Because unlike ios, i keep my apps in app drawers, and not in infinite cluttered homescreens
