It is made for hanging folders, but if you just remove the bars then it is an excellent kabinet for storing your reference material.
I use the top drawer with hanging folders for my tickler files
the bottom two are for reference material.
I use what they call 'binnenmappen'. You can get them here. They are the closest to manilla folders I could find. I have bee using those for 5 years now.
I'm curious, what is used in other countries if not manila file folders? Is there some other common 'standard' thing? They're taken for granted here, in my eyes.
I was lucky that we have a good office supply lady at work who managed to find manila folders from our supplier...
I got many strange looks the day I carted a filing cabinet in to my office when I started with GTD (2 months ago), but that was nothing compared to their shock upon seeing my manila folders! haha
Manila folders are as common as apple pie where I come from, but Everybody uses hanging folders here in Norway.
I get mine from www.binders.no where they are called "vertikalmappe" A4 POS. 1 are the standard ones with the tab on the left, POS. 2 for middle tab, POS. 3 for right tab. They come in boxes of 100.
