[SOLVED] How to open a project by zip?

How to open a project by zip?I have export an index.html for my server to run,but now I want to import my old version into my playcanvas,so how to deal with this operation?

You can’t do it via the built files for hosting unfortunately.

The export/import method is via the zip that I s produced when you export the project (the project structure is fully retained and you get all the original files and source unlike the built files for hosting)

If you are looking to go back to an old version of the project, I recommend using the version control built into PlayCanvas and commit changes on a regular basis https://developer.playcanvas.com/en/user-manual/version-control/
