Did DEC EVER provide a defragmenter?

There is at least one but AFAIK it's user written freeware.  I first 
encountered it ca. 1985-1986.  Before that, I had to do a full backup 
and restore of an RA81.  AIRC it took fourteen tapes and eight to ten 
hours.  The before and after comparison of system performance was amazing.

After the first time disk fragmentation brought my system to its knees, 
I paid a lot of attention to programs that created files and making sure 
that programs that created large files did not allocate them three 
blocks at a time!
