If you upload PDF files onto Sakai on a regular basis, you will realize the Sakai sometimes will not accept large PDF files. Instead of splitting the file into several smaller files, I suggest that you optimize the file, which will reduce the size of the file while keeping the full content.
Here is a quick tutorial on how to optimize a PDF file.
First, open the original PDF file with Acrobat Pro (Right click on the file -> open with). Then, choose: File -> Save as -> Optimized PDF.
A window should come up. You can customize your settings in this window. However, if you are not too picky about the setting, just click ‘ok’.
Then, save the new file.
You should have no problem uploading the new file onto Sakai.
Good luck!
