On Linux and some other Unixes, you can probably read the /proc filesystem.

On Windows, you'll probably get the quickest result by running 
handle.exe (http://www.sysinternals.com/Utilities/Handle.html).

Either way, the information you'll get is restricted by your permissions.

Either information will get stale really fast, so it's not suitable if 
your task is something like 'can I backup this directory or is someone 
writing to a file?'
