.DCF File Extension

Media file encoded with DRM (Digital Rights Management) copy-protection; used by some cell phones for saving protected ringtones, pictures, videos, and other media clips; similar to a .DM file, but the rights object, which allows the encrypted data to be played back, is contained in a separate file.

Because DCF files are saved in a protected or "locked" format, they can typically only be opened using an authorized DRM-compatible cell phone.

File encrypted by Safetica Free, a program used for securely encrypting important data; may incorporate encryption algorithms such as Blowfish, Twofish, CAST5, CAST6, MARS, RC5, RC6, Rijndael (AES), and Serpent; may be password protected.

NOTE: Safetica Free was formerly called DisCryptor.

Disk image created with Disk Copy Fast, a disk copying program for DOS created by Chang Ping Lee in the 1990s; used for duplicating floppy disks; supports DMF, XDF, FDFORMAT, 800KB, and Mac formats.

Disk Copy Plus, the commercial version of Disk Copy Fast, also reads DCF files.

Standard data sharing format used by PriMus-DCF, a program for creating and publishing price lists, estimates, and bills of quantities; contains all the necessary data in a single compressed file.
