Creating a URL Path String

I am trying to use code to create a URL string to an existing file that is in an HTTP compliant folder. However, if the file name has spaces in it the page displays as a blank page. If I rename the file without spaces it works great. How can I use the file name if it does contain blanks, which I am sure the user will use?

A space is an illegal character in an URL.
You need to encode the URL using java.net.URLEncoder.

Though spaces should be avaioded in URL, %20 is hexadecimal representation of "space". Meaning for each space character %20 is substituted

Uh, %20 is just the URL encoded value of a space.

I would add, I now realize that you're posting this in the HTML/JS forum, the JS counterpart of URLEncoder is encodeURI.
 
I agree. Here's the link: http://aspose.com/file-tools
