.DCF File Extension

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.

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.

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.
