Default [Q] CWM Nandroid Backup Categorization (Blobs)

Hey everyone.
I have a question concerning CWM Backups. There are two folders.. "Backup" and "Blobs".
As far as I have realised, "Backup" Folder includes the requiered files to restore, while "Blobs" folder has the main "backup files" of each backup (rom,kernel, apps, data, etc).
Due to lack of storage (and for safety reasons), I want to copy and categorize backups to my pc.
Here's the thing:
Since "Blobs" folder contains files from every back up i make, how can I seperate them so i can successfully and properly categorize them?
