This is a dupe of something asked several years ago and never answered. I have the same situation and need help finding a solution.
The SP site I'm working on has a few files that are updated periodically. I've been asked to find a way to add a link to them in a Links list webpart on the landing page that doesn't require a manual update every time the date in a target filename changes.
The target files all have a fixed location and most of their filenames are fixed. The date portion of the filename changes periodically and irregularly.
We can't add anything from the SharePoint store (heaven forbid we find an easy solution) or use jQuery.
Any leads are greatly appreciated.
