Bug description

Move/Copy hanging up the browser and fails at all, when moving/copying into a folder with large file count

Steps to reproduce

1. Try to move couple of hundred files into a folder with some 30-40+ thousand files.
2. Browser hangs for long.
3. Even if unhang, copy/move will fail anyway.

Expected behavior

Shouldn't hang. Should copy or move.

Well, when selecting the destination, there is no point to list any files whatsoever. You just choosing a folder where to copy or move.

Now as of operation itself. I don't know what is it doing, but I suspect it tries to built up a file list in UI for each operation. If so there isn't need to do it as well. PHP has a function file_exists that is enough to check if something needs to be overridden.
