You should keep in mind that TMG does not maintain your data in a dataBASE
file. Instead it uses a dataSET to store data. A dataSET consists of many
dataBASES that are all tied together by pointers and indexes. Thus the
deletion of one of the dataBASE files causes the TMG internal tests to give
an error and require the running of the Repair function. The internal
tests are TMG's way of maintaining the internal integrity to insure the
safety of your data. So when you delete a file (even if it only contains
deleted data), the Repair function may have to "jump through hoops" to try
to fix the problem because the dataSET is so inter-twined.

Thus in your case, the idea of copying also includes some "packing" of data
(optimizing), but on a more complete basis in that only valid (meaning not
deleted) data is copied. This give you a new dataset with only current
undeleted data in it.

Hope this helps -
