public static void ImportAsset(string path, ImportAssetOptions options = ImportAssetOptions.Default);


Import asset at path.

This imports an Asset at the specified path, and triggers a number of callbacks including AssetModificationProcessor.OnWillSaveAssets and AssetPostProcessor.OnPostProcessAllAssets

All paths are relative to the project folder, for example: "Assets/MyTextures/hello.png"

See Also: ImportAssetOptions.

var relativePath = "Assets/Artifacts/test_file01.txt"; AssetDatabase.ImportAsset(relativePath); } }
