What file format does LIBPF use to save flowsheets ?
LIBPF does not write any data to disk as individual files.
There is a relational database that stores all informations and makes objects persistent. Depending on the underlying RBDMS (Relational DataBase Management System) this database can actually exist as a single file or as a collection of files.
For example the demos of LIBPF 0.9 that you can download from the Process Library are based on Microsoft Access as RDBMS, and you can see the database file (*.MDB format) at the location C:\Documents and Settings\Your Profile Name\Application Data\LIBPF 0.9.
