Use the spaces between columns. The back row is fixed, but the front row is able to be slide.
Lateral sliding shelving can maximize office area and file storage capacity to solve both space and access problems, since two rows of filing equipment are placed in nearly the same way.
There are two Lateral sliding shelving available: Bi-File Sliding Shelving and Tri-File Sliding Shelving (a three row configuration).
The idea behind how Lateral sliding shelving works is simple. Take a row of stationary lateral shelves, and then put another row directly in front of them.
Moving and relocating either Bi-File Sliding Shelving or Tri-File Sliding Shelving is simple
