Then what is the function of this DCIM? If you shoot from a digital camera or from a smartphone. when you want to take the picture to move to a PC, maybe sometimes there is a confusion, especially when using a smartphone. So when you're looking for that photo, it's in a folder called DCIM, and inside the DCIM folder that you can find your photos. but for the smartphone sometimes in the DCIM folder there are several other folders with different names. Especially when you install other camera apps.

Directory and file structure of DCIM Folder Android and Digital Cameras
The filesystem in a digital camera contains a DCIM (Digital Camera IMages) 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 "DSC_", "DSC0", "DSCF", "IMG_", "MOV_", or "P000"), followed by a number. 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 "DSC_" or "DSC0").

The file extension is "JPG" for Exif files and "THM" for Exif files that represent thumbnails of other files than "JPG". Other file formats use different extensions. Multiple files sharing a number (even if the file extension or the four alphanumeric characters are different) are considered related and form a DCF object. Prior to the introduction of DCF 2.0, some camera vendors (e.g. Minolta and Konica Minolta) chose to use the file extension to indicate the recorded color space, that is, "JPG" was used for sRGB, whereas "JPE" was used for Adobe RGB.

For example, the files on a Nikon D40 are arranged according to the above specification. Thus, a card formatted by the camera will have a volume named "NIKOND40", with a subdirectory named "DCIM". This directory contains a subdirectory named by default "100NCD40", in which images are stored. Images are named "DSC_xxxx", where xxxx represents the file's sequential number.

As this is an industry standard, similar directory structures and naming procedures can be found in most digital cameras.

An example of DCF directory and file structure:

Drive > Root > DCIM (directory) > 100ABCDE (a DCF directory)
  • ABCD0001.JPG (a DCF basic file or DCF optional file)
  • ABCD0002.JPG
  • ABCD0003.TIF (a DCF extended image file)
  • ABCD0003.THM (a DCF thumbnail file for extended image file; it is not allowed for ".JPG" files)
  • ABCD0004.WAV (a DCF object need not include an image file)
  • ABCD0005.JPG
  • ABCD0005.WAV (a DCF object formed by naming non-image file with the same file number as an image file)
  • ...
  • ABCD9999.JPG
  • README.TXT (other file names and extensions may be assigned freely)
Drive > Root > DCIM (directory) > ETC (directories other than DCF directories are also allowed; they shall not have the same name as DCF file)
  • ...
Drive > Root > DCIM (directory) > 999ABCDE (a DCF directory)
  • ABCD0001.JPG (a DCF basic file or DCF optional file)
  • ... etc.
