aftershokk,
You probably have some code in your app's startup that does a
Compact/Repair.
When the Compact/Repair finishes, it can't delete the current
database because you're using it. So it adds the "1" to the
DB name.
If you don't delete the "1" version, you'll probably see a
"2" version (and so on).
The "1" version is probably identical, only smaller.
Or maybe the DB Compact/Repairs on exit and for "some reason"
can't delete your original DB file.
hth,
Wayne
