Is it possible to access information on the speed at which a file is being written during a file operation? Many scripts have relied upon simply timing the file operation itself then dividing the file size by the result, but this can only be done upon completion of the operation.

I can only think of splitting a file up into a number of arbitrarily small files so that calculations can be made after each smaller file is operated upon, and merging the small files together at the end. But I presume this would increase the overall time for the operation considerable, especially if the quantity of files or file sizes were large.

I think I'm probably missing a trick here so if anyone can point me in the right direction, I'd be very grateful.

Thanks

To find the time it takes to write a file, I would do it this way:


I get a feeling this isn't what you mean, but without a clearer explanation I can't help more than this.

Thanks - what I mean is, for example, when my script is copying a 4GB file, I can get info on how many MB/s the file is currently copying at.

I don't know off the top of my head, and 10 minutes of Googling has yielded nothing useful.
I don't have the time to really find your answer at this time, maybe next month.

If I did have the time I would use Google and the Microsoft website.
Here are some keywords that may be useful:
Download Rate
Download Speed
Bytes Per Second
Kb/s

Good Luck.
