3.5 Update existing catalogs

When you catalog a read-only disk like a DVD-ROM, the content of that volume can never really change. But the contents of all other volumes can change all the time.

To keep NeoFinder aware of any such changes to a volume, it is necessary to
update the catalog from time to time.

Fortunately enough, NeoFinder makes that a very easy task. There are several ways to update a catalog.

1. Select an existing catalog in the main window and use the "Update Catalog..." command in the File menu or context menu. If the volume that this catalog belongs to, is online, NeoFinder will simply update the catalog. If the volume is not available, NeoFinder will ask you to make it available or insert it.

You can even select multiple catalogs for this command, and NeoFinder will update them one-by-one.

2. If you attempt to create a catalog of a volume that has already been cataloged, NeoFinder will detect that and ask you if you wish to create a new catalog, or update the existing catalog.

What is the difference between updating a catalog, and creating a new one?
Well, when updating a catalog, NeoFinder keeps the catalog comment and name. Also, all comments and labels for items inside the catalog are preserved, so if you have used comments a lot, you won't have to enter them again. Even during an update, NeoFinder will change the volume icon to the currently used one, and of course update volume statistics such as the free space on the volume.

The unique
QuickUpdate dramatically increases the speed of the updating, especially if any metadata or thumbnails are involved. NeoFinder accomplishes that by simply keeping the existing metadata and thumbnails of unmodified files, and is thus a lot faster. This feature is active by default.

You can even update your catalogs automatically
at a given time, by using the AutoUpdater

Stored Cataloging Settings
With NeoFinder 7, your cataloging settings are actually stored inside the catalog itself. So when you update an existing catalog, your original cataloging settings will be used again. That is great as it will make your that your thumbnail sizes are the same after the update, even if you have changed the global cataloging settings in the preferences in the meantime.
However, how can you then change these settings for the update? NeoFinder adds a new button to the Inspector of your catalog. It is called
Cataloging Preferences, and it will display the settings used to create this catalog. You can edit them, and these changes will then be used for the next updates of this catalog.
