At the moment, I am running the Tablebase Generator to create files that were
not loaded from the 9 disc set, because I reinstalled my O/S and the copies of
Generated Tablebase files that I had on DVD were no longer on the DVD I had
copied to months ago.
At that time, I also Generated the missing files. I don't remember if one
particular file took as long as I have been referring to.
Perhaps I just did not realize that one file in particular took so long,
thinking I was just waiting for a number of files.
This time around, I just happened to notice that there is one file taking this
lond.

Obviously, it Generated last time.

The only other possibility that I can think of.......Is that for some reason
this particular file did not load off of the CD......And last time it did.
Perhaps I should go back to my CD Set and check to see if the KRPKQ files are on
one of the 9 dics I have.

I have 2 sets of 9 discs due to an error of a double mailing when purchased.
Perhaps one of the 2 sets is missing something due to a defective CD.

I remember last year that one of the 2 sets did not load properly from
particular CD, so I used the other, not thinking anything of it.

I will have to look into that.

At the moment, it has gone beyond 53 hours. It is now upto  Starting Major
Iteration 35.

I know in the past the Generations took about 4 or 5 days to complete the
missing files.
Perhaps not realizing that one set of files took more than half of the time.
