It seems that we call osl_copyFile() to copy from /assets on Android
in some cases.

Set uid and gid to that of the process, atime to current time, mtime
and ctime to the modification timestamp of the archive entry.

it seems there are two 'unorc' files - confusing huh ?

osl_copyFile is not implemented for android yet, and we can pre-can this dir.
