They could be left only if engine was not shutted down correctly.

fb_sort_XXX files left means application was crushed.

fb_lock_XXX files are per database and will be reused at next connect.
I don't think it is an issue unless you works with different databases
every time. Note, since v2.5 Firebird embedded doesn't put lock files
into temp folder, so this files was left by another embedded Firebrid
version.

Make sure you close all attachments before program exits. It would be
the best if you call fb_shutdown() before exit. Also, you can cleanup
that files at your program startup before first call of ISC API.

It must work. Sooner of all engine can't find firebird.conf. For v2.5 it
should be placed at the same folder as fbembed.dll.
