I tried to copy the file using low-level file functions, and reporting the progress at about each 2.5% of the total. However, it seems that the OS simply queues copy requests - it reaches 100% in a couple of seconds, and only when I issue fClose() on the target file, it then waits whatever it takes until the actual copying happens. Which basically makes my progress indicator useless.

I knew there would be some beast like that. Frankly, heavy artillery of that kind is exactly what I wanted to avoid. Looking for something simple. If it's closing the output file every meg or two, I'll do that. Just no APIs, nothing to install, no extras - this is something that has to run on a server that nobody's looking at. It only has to show to the Citrix user how it's progressing.

Thanks, anyway.
