well, here is my experience with this app: - first I tried it to open a relatively small MBD with around 5k rows? very good, I can see them now. - next I exported them into sql, fine. - then tried it on the largest file I have, it has around 300k rows. nothing happened for a long time, so I walked out and did my shopping…when I came back, it was done. conclusion: this app is very useful when you need to frequently open and do some work on a bunch of relatively small database. If you need to work on oversized database, do it with microsoft access
