How are you determining how much space it takes? Have you looked at the total disk space available before and after making the file?

The reason I ask is that some of the *DBM mechanisms use "holey" (sparse) files where their size is bigger than the amount of disk blocks they actually take. If there is a block that is totally empty, it doesn't use up a disk block even though it shows up in the file size.
