These can have other effects too.

I have my &PH& file as a type 1. I hadn't cleared it out in a long time,
and it collected around 200,000 Id's. Not much per se. But that was 200,000
very little unix files inside that directory.

Enough to cause a hugh 12-13 hour timeframe when I was setting up a
differential
backup. It had to check 200,000 files in that one directory for changes.

This is on any system, not just t64.

If you do go type 1/19 keep a check on the qty of items.

Once I trimmed the qty from 200,000 down to about 800, the differential check
went from 12 hours to 15 minutes.  (I had a few accounts with large &PH&'s)
