<h3>Where are the Database Files Stored?</h3>
<p>
If the base directory is not set, the database files are stored in the directory where the application is started
When using database URLs like jdbc:h2:~/test, the database is stored in the user directory.
For Windows, this is usually C:\Documents and Settings\&lt;userName&gt;.
If the base directory is not set (as in jdbc:h2:test), the database files are stored in the directory where the application is started
(the current working directory). When using the H2 Console application from the start menu, this is [Installation Directory]/bin.
The base directory can be set in the database URL. A fixed or relative path can be used. When using the URL
jdbc:h2:file:data/sample, the database is stored in the directory data (relative to the current working directory).
