How do I convert a database to PGN format?

There are a couple of ways to do this. The most straight forward way is as follows

  1. Go to the browser pane, and simply right-click over the database that you want to convert.
  2. Then select "Save as...".
  3. In the dialog box that pops up, select "Portable game notation (*.pgn)" in the "Save as type" drop down list.
  4. Type in the name you want for the database in the "File name" field.
  5. Hit the "Save" button.

Another way is to create a new PGN database, and copy the files into it. 

  1. On the main menu, select "Base" and then "New".
  2. In the dialog box that pops up, select "Portable game notation (*.pgn)" in the "Save as type" drop down list.
  3. Type in the name you want for the database in the "File name" field.
  4. Hit the "Save" button.
  5. Select the games you want to convert by clicking and holding the left mouse button over the database, game or dataset icon in the browser pane.
  6. Drag the games over to the new PGN database and release the mouse button.

How do I copy games into a database?

This is done using drag and drop.

  1. Open the source database containing the games you want to copy. When you do this, a dataset containing all the games in the database will be created.
  2. Open this dataset, and select the games you are interested in. This is done by consecutively clicking on the game numbers in the left hand column of the view window. As you do this, the games you select will turn blue.
  3. Click and drag the games to the new database in the browser window.
  4. CA will ask you if you want to copy the games to the new database, click on the "Ok" button.

How do I permanently delete games from a database?

  1. Open the database containing the games you want to delete.
  2. Select the games you want to delete by clicking on their game numbers. They should turn blue. 
  3. Right-click over the games, and select "Delete".
  4. Select the main menu item called "Base".
  5. Select "Operations".
  6. Select "Remove deleted games".

How do I open Chessbase Databases?

Chessbase format databases are opened just like any other type of database. Chess Assistant can read both CBF (old format) and CBH (new format) files. However, it cannot open .cbv files, which are compressed, and possibly encrypted as well. To open CBF or CBH files:

  1. Select "Base" from the main menu.
  2. Select the menu option called "Open".
  3. In the resulting dialog box, select the appropriate type of chessbase files from the "Files of type" drop down list.
  4. Navigate to the directory where the Chessbase format file is stored, and double click on it in the file window of the dialog.
  5. You should see a new icon in the browser pane. Note that the icon will have a "RO" next to it. This means read-only. So you can't modify Chessbase format databases, but you can copy games from them.

What does EPD stand for?

EPD stands for "Extended Position Description". It is most commonly used to store test suites. These test quites are mostly used to benchmark, and to test chess engines. Chess Assistant uses them internally for many tree functions. Generally speaking, the average user never has to use EPD files.

What does PGN mean?

PGN stands for portable game notation. It has the advantage of being an internet "standard" for game exhange and storage. This is the format you should use when exchanging games with other people that do not have Chess Assistant.
