Build artifacts
A content build creates files in several locations and Unity doesn't include every file in a built player. Typically, Unity includes files associated with local content in the built player and excludes files associated with remote content.
Most of the files associated with local content are in the Library/com.unity.addressables folder. This is a special subfolder in the Library folder which Unity uses to store Addressables files. For more information about the Library folder, refer to Importing assets.
