Each database in HIARCS Chess Explorer Pro is opened within a tab.

This means you can have multiple databases open simultaneously without having to manage lots of windows.

You can move tabs around by simply selecting a tab and dragging and dropping the tab into a new placement, for example you can drag the MasterBase database tab and place it between the Kasparov-Karpov and Tactics database tabs.

To work on a database simply click on the tab and the database and its display panes will be accessible.

As you will find out HIARCS Chess Explorer makes it simple to have multiple databases open at the same time and this ease and flexibility allows a different approach to analysing and working with databases compared to single game/database programs.

You can close a database at any time by clicking X next to the name of the database tab or by selecting the File->Close menu item which will close the database in the current selected active tab.

We recommend you use the new HCE file format as once a database is in our new format all its operations are near instant.

Please note when opening very large PGN databases it can take some time to load all the games and build the required views of the data. However once the database is loaded even complex position searches are performed almost instantly. Equally when you exit a database tab containing a very large PGN database it takes time to save if changes have been made to that database. For this reason when large PGN databases are opened you will be offered the option to convert the database into HCE format.
