# Persistent storage

Workspace storage that survives between interactive sessions. Files saved elsewhere in a session are lost when it ends.

The rule to remember is which paths survive. Files in workspace storage persist between sessions; session-local paths such as /tmp do not, and neither is readable from a compute node by default.
