Hi, I've noticed a couple of files lying around in my data directory. They seem to be temporary files, with obviously generated names. However, they are substantial in size, some of the being as large as the largest table in the database. The result is that the database is taking up between four and five times more diskspace than it should be. Are these the result of a vacuum? Any ideas would be most welcome, but the main thing is, can I remove these files? Cheers... MikeA
