Alternative File Repository Options

By default, Liferay stores documents and media files on the file system of the server on which it’s running. You can choose a specific location for the document library store’s root directory by adding the following property to your portal-ext.properties file and replacing the default path with your custom path:

dl.store.file.system.root.dir=${liferay.home}/data/document_library

You can also use an entirely different method for storing documents and media files. You can use any of the following documents and media library stores with Liferay:

• Advanced File System Store
• CMIS Store (Content Management Interoperability Services)
• DBStore (Database Storage)
• File System Store
• JCRStore (Java Content Repository)
• S3Store (Amazon Simple Storage)

Warning: If a database transaction rollback occurs in a Document Library that uses a file system based store, file system changes that have occurred since the start of the transaction won’t be reversed. Inconsistencies between Document Library files and those in the file system store can occur and may require manual synchronization. All stores except DBStore are vulnerable to this limitation.

Warning: DBStore’s file (stored as a blob) size limit is 1 gigabyte. To store such large files, use Simple File System Store or Advanced File System Store.

For example, you can store documents and media files in your Liferay instance’s database using DBStore. To enable DStore, add the following line to your portal-ext.properties file:

dl.store.impl=com.liferay.portlet.documentlibrary.store.DBStore

Remember to restart your Liferay server after updating your portal-ext.properties file in order for your customizations to take effect. Please refer to the Document Library Portlet section of your portal.properties file to find a complete list of supported customizations. You can customize features such as the maximum allowed size of documents and media files, the list of allowed file extensions, which types of files should be indexed, etc.
