Looking for auto file size lister to go in html

[SpaceNeedler]

I'm looking for whatever gizmo to automatically list the file size after any document html hyperlink. If it listed file type too, so much the better!
Right now, I have a pdf class in my CSS that appends a pdf icon to links, but I have to hard-code the file size for each link. An automated solution would make maintenance so much easier.
I searched several forums, but only found web site management type solutions (ie, backend directories)- not something to code into my html.
Thanks in advance for any solutions.

Interesting tool - something I might be able use elsewhere later - but not quite what I'm looking for now.
What I want now would be a generic tool (works across the whole site in other words) for individual files, regardless of what file folder they reside in.
