An application for managing your movie collection
GCstar is a free application for managing your collections.
Detailed information on each item can be automatically retrieved
from the internet and you can store additional data, such as the
location or who you've lent it to. You may also search and filter
your collection by many criteria.
GCstar is the successor GCfilms and is compatible to its databases.
As GCfilms isn't developed any more GCstars replaces GCfilms.
