True, you always have to make sure your tools can handle the load. In this case this person wants to move 4,500 db into one. This makes me think that the size of each of the 4,500 db is actually small. If not then he will probably hit the 2G limit of the db. The quickest test would be to see how big the folder is that is holding the dbs. Each db will have some additional overhead that will be gained during the move, but if the folder is below 2G he should be good to go.

As a quick check I generated a empty db. It took up 100k so in its current state he is losing at least.450,000K of space.

Enough of THIS, let's get back to Perl!!!
