I intended to use the product to store files and books but found that its construction is not sturdy enough for the resulting weight. It would be better if it were not as long - then it would hold less paper but would be easier to handle and move and it would be sturdier and provide longer term use. Instead, I now use it to store materials lighter than paper/books, and it does fine for such purposes.
My company has a lot of ongoing projects and at the end of each project we would file the projects in individual boxes and sometimes we would have 2-3 boxes of the same project. The legal size makes it easy to have everything pertaining to this one project in one box and I don't have to go searching for a missing box if they should get separated. Great idea, would most definitely recommend to friends and other organize oriented individuals.
I clean out all files at the end of year and keep only current year in file. The rest goes in the appropriate "box" so it makes old stuff easy to find.
