File and Paths
At you can set options such as what Image Editor (GIMP, Krita…) and Animation Player to use.
The Temporary Directory sets where to store files such as temporary renders and auto-saves.
Tip
The // at the start of each path in Blender means the directory of the currently opened blend-file,
used to reference relative paths.
See File Preferences for details.
Save & Load
If you trust the source of your blend-files, you can enable Auto Run Python Scripts. This option is meant to protect you from malicious Python scripts in blend-files that you got from someone else. Many users turn this option on, as advanced rigs tend to use scripts of some sort.
