    <p><a href="http://www.lingala.net/zip4j/">Zip4j</a> supports creation of split zip file. Here's a sample to create a split zip file (Sample taken from <a href="http://www.lingala.net/zip4j/download.php">Zip4j examples package</a>)</p> <pre><code>ZipFile.createZipFile(File sourceFile, ZipParameters parameters, boolean splitArchive, long splitLength) </code></pre> <p>is the method to create a split zip file. <code>boolean splitArchive</code> has to be set to true in this case. You can set the maximum file size for each split file (z01, z02, etc) via <code>long splitLength</code></p> <pre><code>import java.io.File; import java.util.ArrayList; import net.lingala.zip4j.core.ZipFile; import net.lingala.zip4j.exception.ZipException; import net.lingala.zip4j.model.ZipParameters; import net.lingala.zip4j.util.Zip4jConstants; public class CreateSplitZipFile { public CreateSplitZipFile() { try { // Initiate ZipFile object with the path/name of the zip file.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
