GCstar forums - Record locking

The items database is stored in a regular file (.gcs extension). Such a file could be on a network drive and shared between computers but there would be some risk of conflicting edits.

For this kind of use case, a library management software would probably be better.

To make a copy of a collection, one can export it to an external drive or a archive file (.tar.gz) or simply save it as GCS under a new name (and possibly in a new directory).
