Assetbuild folder

Hello everyone. I’m working on a project and I’ve noticed that our assetbuild folders are getting pretty big. Most of them are several times larger than the total of all the assets in the projects themselves. I was wondering if there was there a way to clean them up or can i just delete the whole folder and have Xenko rebuild it?

To be clear a sample of a bath to the files I’m talking about are \Content…\obj\xenko\assetbuild\data\db\11\b532c9a9ba6884b79da787a4ceec66
