You can extract the file from the library. but you only copy it to other folders as aeric said
B4X: 
    Dim r As Reflector
    r.Target = Me
    r.Target = r.RunMethod("getClass")
    Dim In As InputStream = r.RunMethod2("getResourceAsStream", "/Files/" &  "os.lang.ping.json", "java.lang.String")
    Dim out As OutputStream
    out=File.OpenOutput(File.DirApp, "os.json", False)
    File.Copy2(In, out)
    In.Close
    out.Close
