• [DLL] FileName - specifies the name of the storage file on physical media.
• [DLL] PathSeparator - specifies the separator which will be used in further storage operations.
• [DLL] UseTranactions - set this parameter to True to enable transactions and journalling. Note, that transactions slow down file write operations significantly.
