I've been trying to breakdown the database structure of the new centralized thumbnail database files. Mainly, the "thumbcache_nnnn.db" and "thumbcache_idx.db" files. If anyone has any resources or can help, let me know.
There are a few programs that can display the contents, but I want to know were the data is coming from, how it works.
The databases have an identifier of "CMMM" and "IMMM", respectively.
I've found some great info from Ben Vanik's website/blog.
Hopefully this mystery will be solved, someday. :)
