[SOLVED ] Is Blob files removed on pack (if a site is deleted)? Answer: Yes

If I had a (standalone) Zope with 2 sites and deleted one before starting to migrate the other site from 5.0.something to 5.2.newest: Will the (blob) images and files that were used on site 2 be deleted if I pack the database in the ZMI ?

While packing unused blobs are deleted too.
