Greetings, cygwin AT kosowsky DOT org!

> I literally am typing something like:
>   mv foo bar

> In Linux, that just edits the file system table & inode...

> UPDATE...
> I just tried a second 'mv' and it was near instantaneous.
> (and similarly with subsequent renaming of the same file)
> So perhaps not a 'Cygwin' thing but something going on within Windows.

> Could it be that the first 'mv' triggered an anti-virus read of the file since

> But if so, would 'mv' (under Task Manager) be showing the 100+ MB/s disk activity?

Install processmanager and check what actual activity is happening on that
file. Is it reading or writing? Who is doing that?
