### Remarks

The ratio of `reusedSerializedFileCount` to [ContentSummary.serializedFileCount](/engine/6000.7/script-reference/unityeditor/build/reporting/contentsummary/serializedfilecount.md) indicates what fraction of serialized files were reused versus rebuilt. For Player and AssetBundle builds this value is always zero.
