Is this problem fixed in Windows 7? :)
 
copying multiple small files, and having AV software running plays havok with the figures

if you copy either a large file, or with your AV off, you'll get far more accurate results

don't all OS's do this with multiple small files?
 
It's still rubbish.. last night, its was bouncing between 15hrs and 13 seconds.. and all sorts in-between. was copying lots files over network. took around 20 mins in the end.

How can they get it so wrong ? ftp apps 15 years ago could give a pretty accurate time.
 
It clearly just works on a running calculation of size left vs speed.. to reuse the car analogy, when you're stuck in queues it will alternate between an eta of days when you're crawling along and minutes when you occasionally hit 30mph. It could use a running average, perhaps, which could work out more accurate but it'd be hard to implement well.
 
At least it now tells you how many MB are left (or it does in Vista, I assume it also does in 7), that's much more useful than a time in minutes and seconds imo.

Too many variables to get that kind of figure anywhere near correct, especially if you are trying to update it in near real-time.
 
Would be accurate if they implemented disk image staging before starting the copy off with an image extraction on the other end. Kinda of overkill for the sake of a accurate progress indicator though :P
