Saving CS Illustrator file in script results in much larger file

Question

I would like to use a script that saves a CS Illustrator documents PDF compatible. When I use the script, the created file is much larger (around 3 times) than when I use the Save As dialog box in the Illustrator application with default settings (PDF compatibility and compression turned on).
Dim saveOptions As New Illustrator.IllustratorSaveOptions
saveOptions.Compatibility = aiIllustrator11
saveOptions.PDFCompatible = True
saveOptions.Compressed = True
The script manual setting compressed = true doesn't work. It still
makes a huge file.
I've seen a few other posts here where people have exactly the same problem. Is this a bug in Illustrator DLL?
Please help.

Clearly that's not the entire script since it doesn't run as-is, but that's not the problem.
The code does actually work - at least, assuming your paths are valid it saves the file with the contents you expect. However, your script says:
<pre class=command>set fileSpec to "Photo [Data]:Archive error LOG:" & "test"
save document 1 in fileSpec</pre>
Even though you tell TextEdit to save the file in 'Photo [Data] Archive error LOG:test', TextEdit actually creates a file 'Photo [Data] Archive error LOG:text.rtf'. The filename extension is automatically entered by TextEdit.
Consequently, when you come along later and say:
<pre class=command>open fileSpec</pre>
it's trying to open the filename without the filename extension, and that's where it fails.
Your best solutioni is to use the entire pathname in your variable. That way there's no disconnect when TextEdit adds one that you don't notice:
<pre class=command>set fileSpec to "Photo [Data]:Archive error LOG:" & "test.rtf"</pre>
