Recently I've been copying files from DVDs to network storage on my Mac running Leopard 10.5.7.
I'm just dragging and dropping in Finder to perform the copy.
Occasionally the copy will fail with a dialog complaining that a file is in use. If I repeat the copy generally it completes successfully.
I could understand this being a problem if one was trying to move a file and it was open by another app. But none of these files are open in other apps. I just pop the DVD in, drag and drop the files to my NAS's network share and sometimes it fails with the "file in use" error.
This is very annoying. Anyone have any ideas?

The problem is Quick Look. As soon as you open a folder in the Finder it tries to create previews.
I'm running 10.5.7 and still get this problem all the time transferring video files from external drives. Only solution seems to be to open the folder, wait for the preview icons to appear and then try to copy the files.
A possible solution is to disable "Show icon preview" in the Finder view options. That only occurred to me, so I haven't tested it though.
