Is there an Arabic Easter Egg in Snow Leopard?
Sometimes when copying a large file, a temporary file will be created at the destination. The temporary file could be named &lt;actual file name&gt; &lt;some additional random data&gt;. Once the download completes, the temporary file is renamed to the actual file name.

I'm pretty sure Firefox behaves this way, but not certain whether Finder does. Also, I'm not sure why the suffix was in Arabic; perhaps the random data Apple uses is not limited to just A-Za-z0-9?

Interesting phenomenon nonetheless.
