I had to Google this, and apparently lever arch files are 3-ring binders. I can work with this.
You say you are “ex-students.” So, are these binders something you need to access on a regular basis, or are they holdovers from school days? If you find you need to access them, say, no more than once every few weeks or so, I’d say get them off of display and into storage. Arrange them in alternating stacks (so they lay flat) in some underbed storage, and stash them.
Alternatively, if you never need them? May be time to unfuck them permanently.
