Windows 7: Windows 7 cannot copy DVD with large number of images

What about using something like xcopy or robocopy to do the job, rather than messing with third-party apps?

Meanwhile, you still can use this Microsoft Fix-It Solution...:

Found that RichCopy is improved over the Robocopy gui:

Found back the MS article saying about selecting more than 15 files at the time to move...they do talk about "missing items in context menu" but it is worth a try as it related to.

not sure why the copy stops, but the reason it takes so long is that as it writes each file it verifies that the copy is 100%.

If that's the case then it seems Windows 7 is badly written software. Verifying file copy shouldn't take that long. I'm sure other operating systems are faster than Windows when it comes to copying large numbers of small files such as jpegs.

While researching this issue, it seems that Windows 7 is also slow at copying across a network too: Why is Windows 7 so slow in copying network files?

I am not sure why your copy process stops, but I imagine that 30,000 files will take a while to copy. The read speed of the DVD drive is theoretically 16x10Mbits/s, which is not too high, about 20 MB/s.

Now, do you have all of these files on one DVD? The DVD size is 4.7 GB, which means your average file size is 157 KB (not too large for jpegs). When you copy that many small files in Windows 7, sometimes the copy speed drops to 1 MB/s, in which case it would take you a couple of hours to complete the task.

Whether or not this indicates that Windows 7 is badly written I do not know, but indeed slow copy speeds was my only complaint about the OS. After SP1 these speeds have increased dramatically though.

Finally, what can you do to speed up the process? If I were you I would just make a disk image. Any DVD-related software (such as Nero) or disk image software (such as UltraISO) is capable of making a disk image (i.e. a ISO, NRG, or any other of the gazillion possible formats). This should take a couple of minutes to complete. Moving the image to a back-up disk should also be fast - much faster than 30,000 small files. The disk-image software can read individual files from the image or you could extract all of them in your back-up disk if you need to be able to access those individual files without any software.

verifying doesn't take long at all, it's just that it will do it 30,000 times + the time it takes to copy.

Thanks, Unifex. I'll try making a disk image.

I just tried this using a DVD with about 25,000 images on it and not even a slowdown in the process using Windows Explorer. I have SP1 and no "tweaks" or "fixes." It's not a 7 problem apparently.
