I have some questions about your article:
Can give any indication about the performance of this read action? Where is the greatest restriction in the performance?
Are there any restrictions on the file sizes other than the OS?
And in which circumstances would you preferably use this technique?

Cheers,
Karin

No, it also works for other operating systems (adjust your directory alias accordingly).

What is a “Windows local drive”? A drive local to your database server? A drive local to your database client?
Is the above code only working for Windows?
