I've looked at the threads in this forum, and they mostly talk about buttons or right-click functionality. But what I'd like to do is to make it work when I use synchronize. And I'm not sure how that can be done other than by swapping out DOpus' copy function used by the synchronize function.
The only reason I want to do this, is because I have a problem both with both Windows' and Dopus' copy function. When copying files to USB disks, they will pause after each copy exactly the same time it took to transfer each file. It's almost like they calculate the hash for each file between copies. Which may be what they do, for all I know. Teracopy does not have this problem. I've googled far and wide, but without success.
From what I've seen in other threads, doing the above is probably not feasible, but I'd thought I'd ask anyway.
I suspect the pause you are seeing in Windows/Explorer and Opus is the files being flushed to the USB sticks.
It's possible (just a theory; I have not checked) that Teracopy doesn't do that flush with USB sticks and thus looks like it has finished the file faster when the file is really still in the operating system's cache and still being written to the stick.
(Or it could simply be that the progress bar in Explorer and Opus shows progress writing to the filesystem cache while Teracopy is showing the progress writing to the disk -- e.g. if Teracopy has disabled the cache entirely for that type of drive -- in which case the overall time should still be similar but the progress bars would reach 100% at different times, and in the programs which use caching & flushing it would wait at 100% while the cache was flushed to the USB drive.)
It could also be other differences rather than caching. For example, Explorer and Opus may be setting file attributes which Teracopy isn't, or similar.
I just timed a copying in DOpus vs TeraCopy, and you are correct, they do use the same amount of time. The TeraCopy slider just moves at half the speed. Doh! I should have done that earlier.
Anyway, thanks for your reply! It made it all crystal clear. I simply won't look at the slider anymore when copying.
