Reduce the size of Proview projects

The size of Proview projects can become big.
Especially after using a new version of BerkleyDB

Run the reload.sh script

This script will dump the database in to a text file and reloads it again
Be sure to check after running the script you can open the rootvolume before you delete the copy
You can find the copied database in $pwrp_db/{volume name}.db.1

---

To reduce the size, you can see with wb_ldlist which classvolumes are referenced by your local volumes.
Enter the .dbs file as argument.
> wb_ldlist $pwrp_load/myvol.dbs
Not referenced classvolumes are not loaded in runtime and can be removed.
