I am now remembering renaming directories and then back again,
but I can't remember if it was VMS or TOPS-10.

The system would let you rename them, but would still remember
that they were directories (and not let you delete them).

For TOPS-10 there are SAV and EXE files, and I think the extension
is important, but maybe it can figure it out.

Windows accepts both CMD and BAT for command files.   I believe
it will run executables independent of the extension, though
I am not so sure about command files.
