>I am not sure which version of Firebird you are using. If you have MON$DATABASE table in your db then that will tell you the location of the FDB.

Thanks for the tip. I'm using 2.05.13206 andit doesn't seem to have a table with that name (it does have RDB$DATABASE, but the location isn't in that table. I'm planning to switch to FB 2.5. Do you think that table will be there?

BTW, I listed the tables by looking in RDB$RELATIONS.
