# Where is the Auto Save feature? How do the backup files work?

In "Menu" -> "Preference" -> "General" you can set Auto Save. 

Auto-save is enabled by default, and you can set the interval of it. In "Menu" -> "File" -> "View History Version", you can open the most recent 3 auto-saved projects.

> To use autosave, please save the project once first. A project that has not been saved will not trigger the launch of the function.
