Create Zip When Finished (File=>Export=>HTML)
Click this check box to have GSAK create a .ZIP archive of the files in the Cache folder. This is useful, because it can dramatically reduce the time it takes to transfer the HTML files to your PDA.
When you check this box, GSAK displays a field in which you can type the name of the .ZIP file. Alternatively, you can click the browse
button to select an existing file through a standard Windows dialog box.
