Concertina Files

 

A concertina file expands into a row of labelled pockets that keep loose paperwork sorted in one carry-anywhere folder, the answer when documents are loose rather than punched into a binder. The decision is pocket count and closure. For punched filing instead, see ring binders.

A concertina or expanding file keeps loose paperwork sorted into labelled pockets within one folder you can pick up and carry. It suits documents that are not hole-punched, like receipts, invoices, bills or a month of paperwork, and it is the common choice for tax records, a household filing system or a set of project documents kept together.
A 13-pocket file covers a month per pocket plus a spare, or a dozen categories. A 26-pocket file takes a full A-Z or a pocket per client or per month across a longer period. Count the sections you actually need rather than buying the largest, since empty pockets just add bulk.
Card files are cheaper and fine for a file that lives in a drawer or on a shelf. Polypropylene wipes clean, resists tearing and handles being carried around, so it suits a file that travels to meetings or site. The ColourHide Zip-It range is polypropylene with a full zip for exactly that.
An elastic strap is quick and fine for a file that stays upright on a desk. A full zip closes the file completely so nothing falls out when it is carried flat or tipped, which matters for a file of loose receipts or travel documents. The zip costs a little more for the security.

Expanding files by pocket count

Pocket counts run from around 12 up to 26. A 13-pocket file suits a month-per-pocket system or a set of categories, while a 26-pocket file takes A-Z or a pocket per client. Card files are the budget option, polypropylene wipes clean and lasts longer, and closures run from a simple elastic strap to a full zip that keeps everything in when the file travels. FM, ColourHide Zip-It and Marbig cover the range in A4 and foolscap.

Loose paper, sorted and portable

A concertina file does one thing well: it keeps loose paperwork sorted into labelled pockets inside a single folder you can carry. That makes it the tool for documents that never get hole-punched, receipts, invoices, bills, a month of paperwork or a set of project papers that belong together. Where a ring binder needs punching and a drawer needs sorting, a concertina file holds it all in order and lifts off the shelf in one piece.

Pocket count and closure

The size you need follows how you sort. A 13-pocket file takes a month per pocket or a dozen categories, while a 26-pocket file handles a full A-Z or a pocket per client. Card files keep the cost down for a file that stays put; polypropylene, including the ColourHide Zip-It range, wipes clean and survives being carried; and the closure ranges from a quick elastic strap to a full zip that keeps loose receipts in when the file travels. FM, ColourHide and Marbig cover A4 and foolscap.

Where it fits

For paperwork that is punched and filed long-term, ring binders are the better home, and for a single document on the move a document wallet is lighter. The concertina file sits between them, for a set of loose documents you want sorted and portable. Orders over $30 ship free across NZ.
