There is a problem when you try to delete some pages from a PDF file using Adobe Acrobat 5 will result in no file size reduction.

To resolve it, try the following methods:

1. After editing, save the file as a new file. (don't save to the same file)
2. After editing, use the PDF Consultant to optimize the space. (In Acrobat, click Tools -> PDF Consultant -> Optimize Space with the following settings)Then save the file. (No need to save as a new file)

Note: If you use Acrobat 5 with Win XP, the space optimization will be done automatically every time you save the file.
