Up front I will apologize for the long winded explanation.
To those of you that had a problem with all of the files not extracted, there is a way to get them from the original *.zip file.
First thing you need to do is change the file view settings in folder options so that file extensions are visible. You can change it back later.
Starting with the original Ford_F150_1997-2003_1231.zip file, navigate to the document that did not extract, I will use the Remove-Install-Overhaul.pdf file as an example.
The string is:
Ford_F150_1997-2003_1231.zip/FORD F150 2001 1997-2003 SERVICE REPAIR MANUAL/2001-2003/2003 Repair Information/Engine Performance/Remove-Install-Overhaul.pdf
Open the file. Once the file is open in Acrobat Reader, click save. There may be a dialog box that states that you cannot make changes to a Reader file and that you will only be saving a copy, click "OK". Select the destination of the file to be saved (I chose the same folder in the directory that I saved the manual to), click save.
Navigate to the location you saved the file and it may still show up as non-pdf file with the extension *.pd (About half of them did), right click the file and select "Rename". Change the file extension from .pd to .pdf and hit the "Enter" button. The file will now be a valid PDF file that can now be viewed.
After I typed this, I discovered that some of the files just need to be renamed and add the extension .pdf at the end and all is good!!! In this case, you definitely need to set your folder settings to make file extensions visible or you may wind up with files that have .pdf.pdf which will definitely break them.
The most likely reason this happens is that there is a character limit (It looks to be 25 characters) to a file name with the algorithm that the extractor uses, thus cutting off a portion of the files name and the extension which leads to a file type unrecognizable by the computer.
Try both methods and determine which one works in your case.
