In order to guarantee [[interoperability]], DCF specifies the file system for image and sound files to be used on formatted DCF media (like [[removable media|removable]] or non-removable memory) as [[FAT12]], [[FAT16]], [[FAT32]], or [[exFAT]].<ref name="CIPA2010">{{citation |url=http://www.cipa.jp/english/hyoujunka/kikaku/pdf/DC-009-2010_E.pdf |archive-url=https://web.archive.org/web/20130930190707/http://www.cipa.jp/english/hyoujunka/kikaku/pdf/DC-009-2010_E.pdf |archive-date=2013-09-30 |title=Standard of the Camera & Imaging Products Association, CIPA DC- 009-Translation- 2010, Design rule for Camera File system: DCF Version 2.0 (Edition 2010) |access-date=2011-04-13}}</ref> Media with a capacity of more than 2 GB must be formatted using FAT32 or exFAT.

The [[filesystem]] in a digital camera contains a '''DCIM''' ('''Digital Camera IMages''') [[directory (file systems)|directory]], which can contain multiple subdirectories with names such as "123ABCDE" that consist of a unique directory number (in the range 100...999) and five alphanumeric characters, which may be freely chosen and often refer to a camera maker. These directories contain files with names such as "ABCD1234.JPG" that consist of four alphanumeric characters (often "100_", "DSC0"<!-- f.e. Konica Minolta and Sony -->, "DSCF"<!-- Fujifilm -->, "IMG_"<!-- Canon pictures -->, "MOV_"<!-- Canon movies -->, or "P000"<!-- Olympus-->), followed by a number. Handling of directories with possibly user-created duplicate numbers may vary among camera firmwares.

DCF 2.0 adds support for DCF optional files recorded in an optional color space (that is, [[Adobe RGB]] rather than [[sRGB]]). Such files must be indicated by a leading "_" (as in "_DSC" instead of "100_" or "DSC0").<ref name="CIPA2010" />
