The ones I got seem very flimsy I wouldn't trust them to hold up to frequent use. The lids on mine don't fit well and are don't stay in place against handling. I can't imagine these would be rigid enough to actually hold a full set of files without the hanging folder tabs popping out of place due to the lack of rigidity.
This somewhat clear file box is perfect for me to put files in that I hardly ever need to get into and I just popped it in my upper closet Hangs files perfectly.
