Looks like no one’s replied in a while. To start the conversation again, simply ask a new question.

When I download an Adobe (.pdf) attachment in my AOL mail, using the Safari browser, the links in the .pdf have an appended %20 so the referenced file is not found.

I have an Adobe file that contains hyper links to .pdfs on a website. When the link is selected the file name.pdf%20 is referenced and is

not found--because of the %20 being automatically appended to the file name. This is not happening on other computers.


Sincerely,

Gary-


An %XX number is the hexadecimal code for an ASCII chracter. Such codes are allowed in URLs, but normally only used for characters that would mess up the URL. (Some spammers use them to disguise a URL.)


In this case, I believe %20 is the code for the ASCII Space character. File names can have spaces, but URLs can not have spaces unless they are in the %20 format.


I'm wondering how the %20 was appended to your link, since a URL with a space at the end seems meaningless. Does it happen in other Adobe files, or just that one? Does that Adobe file's link act differently on your computer than on the iPad?

I went into debugging mode and solved the problem which was, in reality, a series of multiple problems.

First, I have all the links on a web page that I copied and pasted into an MS Word (.doc) document. This document

when downloaded as an attachment from my aol e-mail (using the Safari browser), had links that contined "%20t%20_blank" which indicated to me that I should not use <a href="filename.pdf" target="_blank">.


So, when I used only <a href="filename.pdf"> and pasted the web contents into the MS Word file, and attached this .doc file, everything worked fine. If, however, I converted this MS Word file to ADOBE, then the filename.pdf%20 references appeared again.


Thus, the solution seemed to be to attach the .doc file to my aol email (and not use the target parameter in the hyperlink).
