I've selected a very large set of folders in Konqueror and copied them from one disk to another. I'm noticing, watching the progress, that it's blatantly not copying in simple depth-first order. Instead it's fluttering madly all over the directory tree. Coming from the Windows world, I've never witnessed anything like this.
It seems in general to be preferring to copy the hugest files first, working its way down to the tiniest files, but not precisely. It also exhibits a large degree of randomness. It did scan the entire set before it started, so I presume it has some deliberate plan in mind.
What's going on? Is this a strategy for avoiding fragmentation? Is it something to do with the low-level arrangement of files on the source disk? Is it a good idea? I'm irked by it and tempted to manually copy the folders one by one to achieve a less scattered placement, but I don't know if Konqueror is actually doing something clever.
