Shelving unit/cupboard deep enough for A4 files?

[TheLightGetsIn]

I have a lot of files with papers that I need to keep. They are all neatly filed in box files or ring binders, but I now have too many for our current storage and need another unit. At the moment some are in deep IKEA corner shelving units, but those were bought second hand years ago so I have no idea what they were called and can't find anything very similar on IKEA's website. Other files are stored inside some deep cupboard-style shelves with doors, which is my preferred solution but again these ones are years old and I can't find anything similar. Ordinary bookshelves with doors obviously aren't deep enough for A4 files. Does anyone have any suggestions? Should mention that I don't really want filing cabinets (too office-y looking, plus I need more of a floor-to-ceiling solution as I have so many files to store).

I’ve got IKEA kallax for dds school files, they fit top to bottom & depth but they don’t have doors

Ours is 1 row but they do bigger/different shapes

Thank you! I didn't think of Kallax. Also, I've just remeasured and realised that Billy bookcases are deeper than I thought and I think you can get doors for them, so they might be another option.

Yes you can definitely get doors for the Billy bookcase, that might look tidier (unless you are like my Dd & want shelves full of pastel folders just for the look of it!)

You can also get doors (and drawers) for the Kallax.
If your files are presentable, I think they look fine without being shut in!

We use Billys with doors for A4 storage. It looks great and tidies up what would otherwise be very messy shelves. They are easy to assemble and they seem to last forever.

We use kallax and bought the doors for them. Stores loads.
