# Save and close cleanly

`Job.Save` writes the active job to a `.sg` file. The `filePath` works
like Save As — pass any path you want; the file is created (or
overwritten) at that location. Wrap the work in `try / finally` so
`Job.Close` runs even if a step in the middle throws, otherwise the
service is left holding an active job and the next `Open` will
return `409`.

The snippet below opens the `Portal Frame.SG` sample, saves it as a
new file on the desktop, and closes the job — useful as a template
for any "open something, save it as something else" workflow.

If you want to save to the path the job was originally opened from,
omit `filePath` — the API saves over the original. (Sample projects
opened with `Job.OpenSample` are unsaved and have no original path,
so you must supply one.)
