Site-wide File Root

The site-wide file root is the top of the directory structure for files you upload. By default it is the same as the LabKey Server installation directory, but you may choose to place it elsewhere if required for backup or permissions reasons.

During server setup, a directory structure is created mirroring the structure of your LabKey Server projects and folders. Each project or folder is a directory containing a "@files" subdirectory.

You can specify a site-wide file root at installation or to access the "Configure File System Access" page on an existing installation, use Admin > Site > Admin Console > Files.

When you change the site-wide file root for an existing installation, files located under that site-wide file root will be automatically moved to the new location. The server will also update paths in the database for all of the core tables. If you are storing file paths in tables managed by custom modules, the custom module will need register an instance of org.labkey.api.files.FileListener with org.labkey.api.files.FileContenService.addFileListener(), and fix up the paths stored in the database when its fileMoved() method.

Files located in projects that use pipeline overrides or set their own project-level file roots will not be moved. Please see Troubleshoot File Roots and Pipeline Overrides for more information.

Project-level File Roots

You can override the site-wide root on a project-by-project basis. A few reasons you might wish to do so:

• Separate file storage for a project from your LabKey Server. You might wish to enable more frequent backup of files for a particular project.
• Hide files. You can hide files previously uploaded to a project or its subfolders by selecting the "Disable File Sharing" option for the project.
• Provide a window into an external drive. You can set a project-level root to a location on a drive external to your LabKey Server.

• From your project:
• Select Admin > Folder > Project Settings.
• Click the Files tab.

• Click Save.

You can also see or set the project-level file root by selecting Admin > Folder > Management and opening the Files tab.

Named File Sets

Named file sets are additional file stores for a LabKey web folder, that exist alongside the default file root for a web folder, enabling web sharing of files in directories that do not correspond exactly to LabKey containers. You can add multiple named file sets for a given LabKey web folder, displaying each in its own web part. The server considers named file sets as "non-managed" files systems, so moving either the site or the folder file root does not have any effect on named file sets.

To add a named file root:

• On the Files web part, click the dropdown triangle next to Files and select Customize

• On the Customize Files page, click Configure File Roots.
• Under File Sets, enter a Name and a Path to the file directory on your local machine.
• Click Add File Set.

• Add additional file sets are required.
• To display a named file set in the Files web part, click the dropdown triangle on the Files web part, and select Customize.
• On the File Root dropdown, select your named file set, and click Submit.

• The Files web part will now display the files in your named file set.

For details on URL parameters used with named file sets, see File Sharing and URLs.

For details on displaying a named file set using the JavaScript API, see JavaScript API - Samples.

Summary View of File Roots and Overrides

You can view an overview of settings and full paths from the "Summary View for File Directories" section of the "Configure File System Access" page that is available through Admin > Site > Admin Console > Files. A screenshot:

File directories, named file sets and pipeline directories can be viewed on a project/folder basis through the "Summary View." The 'Default' column indicates whether the directory is derived from the site-level file root or has been overriden. To view or manage files in a directory, double click on a row or click on the 'Browse Selected' button. To configure an @file or an @pipeline directory, select the directory and click on the 'Configure Selected' button in the toolbar.
