Why do link addresses change, and how frequently does it happen?

[CarthagoDelendaEst]

I have several files on my Creative Cloud account which I share with clients with the links provided on the site by posting the link on my website.  Those links keep breaking because the link to the file changes.  How frequently does this happen?  So I know when I need to go through and change them all over again.
