Blender file too big!

I blender file is like 2GB big. Is there anyway I can reduce the size?

You can purge orphan data and then save (make sure that there aren’t any fake users e.g. for textures). This will delete unused data. You can also save as a compressed blend file, but that makes saving slower each time. Using instancing and data linking also reduces file size, if there is data that’s repeated.
