 ## Key details
 
-### Managed data directory
-
-`PI_WEB_DATA_DIR` selects the machine-global root for PI WEB-managed state. It defaults to `~/.pi-web`. Session archival uses this layout:
-
-- `$PI_WEB_DATA_DIR/archived-sessions.json` for the archive index.
-- `$PI_WEB_DATA_DIR/archived-sessions/` for archived session files.
-
-The session daemon owns both archive locations. Restart the session daemon after setting or changing `PI_WEB_DATA_DIR`; restart the web/API process as well so its other managed-state stores use the same root.
-
-PI WEB does not move existing managed state when `PI_WEB_DATA_DIR` changes. Stop the session daemon and back up the source and destination before moving archive data manually. The archive index stores absolute `archivePath` values, so update those values when archived files move to a different path.
-
 ### External path access
 
 `pathAccess.allowedPaths` grants PI WEB's file explorer and absolute `@` path completions access to specific filesystem roots outside the current workspace.
