The accordion-style sides of these pockets are too short to use easily with wire frame file inserts (e.g. Staples own OIC® Hanging File-Folder Frames.) As with all other expanding hanging file jackets that I know of the sides of these hang under the wire frame when the user tries to lift them up and out. Unless your file drawer has solid sides from which to hang the pockets you will have problems.
My client folders were getting very large due to having to keep all the printed recipes for each cook day. This expandable folder is flexible and made of plastic so it won't rip or tear. It can even be wiped clean if I get food on it! Love it!
This product is used to keep large amonuts of business papers organized. Because this product is made of poly and expandable I can remove it from the file cabinet to insert into my briefcase when I'm on the go. This is a great product.
