Handling home office equipment - hanging files

We are spending several months at a time in our RV. I have tried numerous ways of keeping personal files. My hanging files jump off the rails while traveling and fall down into any file drawer, file box or file container I have tried. Anyone have a hack for keeping the files ON THE RAILS? I have seen hacks with clips to keep them from sliding, but I want them to STAY ON THE RAILS. Any ideas???
