you misunderstand Bob, in 7k format you can transfer 20 files to a folder in one go because you can fit 20 files on a floppy. In 5k format you cannot fit 20 files to a floppy and thus have to do all the individual file copying and then deleting you talked of in order to fill a folder with 20 files. All this is unnecessary if you plan your folders in advance with the 20 files you want on each floppy. Then all the moving is not necessary. When I wanted 20 customs in the one folder, the individual moving was by far the most time consuming part of the job, therefore anything to remove this is a big bonus.
If you want to rename in the conventional manner on the 7k you have to load and save anyway but that's not what I described.
I've done many backups, merges and restores and it works well.
