It's probably stored as an incidental bit of data in the attributes.  
The attributes may not be in the directory, they're more likely to be  
in the stored file. So you'd need to write code to put attributes in  
the directory for all files, and then decrypt and display them.

I have considered the exact file size a secret, although of course  
you can work it out to within a few percent.
