Confluence ホームディレクトリとは?

The Confluence Home directory is the folder where Confluence stores its configuration information, search indexes and page attachments. If you're using the embedded HSQLDB database supplied for evaluation purposes, the database files are also stored in this directory.
(tick) Tip: Another term for 'Home directory' would be 'data directory'.

You can also read about the contents of the Home directory.

Confluence ホームディレクトリの見つけ方

The location of the Confluence Home directory is defined when you install Confluence. This location is stored in a configuration file called confluence-init.properties, which is located inside the confluence/WEB-INF/classes directory in your Confluence Installation directory.

When Confluence first starts up, it reads the confluence-init.properties file to determine where to look for the Home directory.
