Is there a way to have defraggler just do the move large files of a certain file type to the end of the disk, without it defragging all the other stuff? I know that's not the greatest of ideas, but it might be beneficial if you only have a little amount of time and want to get a head start on a large disk defrag, where you can start to just move the files to the end of the disk and defragment them.
If there is a way, I haven't found it. In general this would not make sense, because you could have files which would be compacted at start of disk by defrag, in the area the large files shall be moved to which is likely to cause fragmentation and increase the total amount of work, as later the hole will need re-compacting the "end of the drive" meaning large files are likely to be shifted up.
