Devices

Summary​

This page describes the concept of Device in Katalog and the top part of the Devices screen.

In this example, several catalogs have been created from 2 physical drives.
The catalogs with photos/images/pictures have been assigned to a virtual Photos device.
This gives a way to search in these only, and it provides totals of number and size of photos files.

Model​

Definitions​

  • A Catalog device is a list of files in a particular directory.

  • A Storage device is a physical drive on which files are stored. Typically it is "mounted" or "connected" to the computer, and it has physical storage space.

  • A Virtual device is any non-physical item used to group other devices together. It has no properties on its own and can aggregate numbers from the related sub-devices.

  • A Group is a virtual device at the top of the hierarchy.

    • The Physical group is a unique and reserved group for the hierarchy of physical devices (computer, phone, disk, etc.).

    • Any other is a Virutal group to which existing catalogs can be "assigned" to faciliate searching and statistics.

Hierarchy​

Features​

These are always available at the top of the screen.

Chosing between 3 views​

The devices can be listed and managed in 3 ways:

Device Tree: This view is showing the full and unfiltered list of devices in a hierarchy / tree structure.

Storage list: This view is showing only Storage devices and is filtered based on the Selection panel.

Catalog list: This view is showing only Catalog devices and is filtered based on the Selection panel.

Display full table​

Click this option to show all the data available in the view.

If unticked, this is typically hiding data that may not be needed on a day to day basis (ex: internal ID).

This may help keeping a simpler and more readable view.

Record a snapshot of the data​

This button trigger a record all devices values (size, files, space, etc.) independently of the current selection.

These records support the creation of Statistics, and particularly to keep track of the collection globally, and independently of the individual device updates.
