How big is the .DIR file after you've created those temporary 10 MB files ? Would it help, to DELETE/ERASE those files in reverse order, i.e. highest version number first ? This would reduce the shuffling of entries in the directory.

If he has a range of filenames, version numbers will not be the only issue
here, but also the ordering of the filenames in the directory file.

He needs to delete files in reverse name order _and_ for a given filename
needs to delete those files in reverse version number order as you say above.

Hard to believe that this is still a problem on VMS in 2021.
