unable to unzip a large PDF file on my iphone.

I am unable to unzip a large PDF file on my iphone.  I have unzipped it on my computer.   The topographical maps are too large to transfer to my iphone, so downloaded zipped file to phone.

Anyone know the best app to extract files on my phone?

Thank you

Maybe the PDFs just can't fit on yourn iPhone. Which would mean you couldn't unzip them because there isn't room...
