Environment variables

  • LONGPATH_CONFIG Path to longpath.toml (java_home, mpxj_classpath, max_rows, allow_writes). Optional: .xer and MS Project XML need no config.
  • LONGPATH_HOME Folder searched for longpath.toml when LONGPATH_CONFIG is not set (default: a longpath folder in %LOCALAPPDATA%, or ~/.local/share/longpath).
  • JAVA_HOME A Java 11+ runtime, used only to open .mpp / P6 XML files through MPXJ (install longpath[mpp] for the MPXJ jars).
