Until the folder is expanded to its full size the accordian folds make it difficult to insert papers...Plain hanging folders without the sides are easier to use though not collapsible.
I just like this particular expandable folder because works for me. It is a strong sturdy folder and won't ware out easy. Don't have to worry about my items falling out either.
The metal parts that hook the folder onto the file frame won’t stay out so the files keep falling off the track. They are useless. I wasted my money because I didn’t keep the packaging.
