The folder is to thin. If I had known how thin it was I would have bought something else. Some of my files have a lot of paper to be put in the folders and we store it in the folder for several years. I need to make sure the folder is going to be able to hold all the papers and not and stay intact within those several years.
The medium duty folders are great for low use files. Since they are not used every week heavier duty files are not needed. Plus they are less expensive. Will buy again when needed.
