,
*.db
,
*.px
, which
are created automatically when a new database is created (see
also File types of VA Database, page 5). All changes in the data-
base will be stored immediately to this 4 files on the hard disk.
Note: These four files on the hard disk should never be renamed
with the Windows Explorer or another file manager tool. For this
purpose the function
Save Database As...

The current working database may be different from databases
opened in background for data transfer (see Data transfer, page
