.mds
Media Descriptor File (MDF) is a proprietary disc image file format developed for Alcohol 120%, an optical disc authoring program. Daemon Tools, CDemu, MagicISO, PowerDVD, and WinCDEmu can also read the MDF format. A ''disc image'' is a computer file replica of the computer files and file system of an optical disc. Unlike an ISO image, a Media Descriptor File can contain multiple layers (as used in dual-layer recording) and multiple optical disc tracks. Like the IMG file format, a Media Descriptor File is a "raw" image of an optical disc. The word ''raw'' implies that the copy is precise, bit-for-bit, including (where appropriate) file-system metadata. A Media Descriptor File may be accompanied by a Media Descriptor Sidecar file. This optional binary file (with file extension .mds) contains metadata about an imaged optical disc, including a delineation of where disc layers begin and end ("layer breaks"), and which portions of the MDF belong in which disc layer.

Alcohol 120%
Alcohol 120% is a disk image emulator created by Alcohol Soft. It can create and mount disc images in the proprietary Media Descriptor File format. Images in this format consist of a pair of .mds and .mdf files. Alcohol 120% can also convert image files to the ISO format. Alcohol Soft has cited it will not be developing an image editor for Alcohol 120%. The latest versions of Alcohol 120% comes with "Alcohol Cloaking Initiative for DRM" (A.C.I.D), which hides emulated drives from SecuROM 7 and SafeDisc 4. Features Alcohol 120%'s image making tool supports the following formats: *Media Descriptor File (default), consisting of a pair of .mds and .mdf *ISO image (.iso) Furthermore, Alcohol 120% can mount the following images: *CloneCD image, consisting of a trio of .ccd, .img, and .sub files *Raw images, consisting of a pair of .bin and .cue files Alcohol 120%'s image recording feature is capable of bypassing certain copy protection schemes, such as SafeDisc, SecuROM, and Da ...

CDemu
CDemu is a free and open-source virtual drive software, designed to emulate an optical drive and optical disc (including CD-ROMs and DVD-ROMs) on the Linux operating system. , CDemu is not available in the official repositories of Debian, Ubuntu and Fedora Linux for any release, but it is available via official Personal Package Archive, PPA for Ubuntu and COPR (Fedora), COPR for Fedora Linux. Components CDEmu consists of: * a kernel module implementing a virtual SCSI SCSI host adapter, host bus adapter, * libmirage which is a software library for interpreting optical disc images, * a daemon which emulates the functionality of a SCSI optical Optical drive, drive+Optical disc, disc, * textmode and GTK clients for controlling the emulator. The software is portable to other operating systems supported by GLib, with the exceptions of the kernel module and the clients which rely on d-bus communication. History CDemu was originally designed by Robert Penz and Justus Schwartz as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disc Image
A disk image, in computing, is a computer file containing the contents and structure of a disk volume or of an entire data storage device, such as a hard disk drive, tape drive, floppy disk, optical disc, or USB flash drive. A disk image is usually made by creating a sector-by-sector copy of the source medium, thereby perfectly replicating the structure and contents of a storage device independent of the file system. Depending on the disk image format, a disk image may span one or more computer files. The file format may be an open standard, such as the ISO image format for optical disc images, or a disk image may be unique to a particular software application. The size of a disk image can be large because it contains the contents of an entire disk. To reduce storage requirements, if an imaging utility is filesystem-aware it can omit copying unused space, and it can compress the used space. History Disk images were originally (in the late 1960s) used for backup and disk clonin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cue Sheet (computing)
A cue sheet, or cue file, is a metadata file which describes how the tracks of a CD or DVD are laid out. Cue sheets are stored as plain text files and commonly have a filename extension. CDRWIN first introduced cue sheets, which are now supported by many optical disc authoring applications and media players. Overview Cue sheets can describe many types of audio and data CDs. The main data (including audio) for a CD described by a cue sheet is stored in one or more files referenced by the cue sheet. Cue sheets also specify track lengths and CD-Text including track and disc titles and performers. They are especially useful when dividing audio stored in a single file into multiple songs or tracks. The data files referred to by the cue sheet may be audio files (commonly in MP3 or WAV format), or plain disc images, usually with a extension. When used for disc images, the format is usually called CUE/BIN, indicating that it stores a disc image composed of one cue sheet file and one ...

Binary File
A binary file is a computer file that is not a text file. The term "binary file" is often used as a term meaning "non-text file". Many binary file formats contain parts that can be interpreted as text; for example, some computer document files containing formatted text, such as older Microsoft Word document files, contain the text of the document but also contain formatting information in binary form. Structure Binary files are usually thought of as being a sequence of bytes, which means the binary digits (bits) are grouped in eights. Binary files typically contain bytes that are intended to be interpreted as something other than text characters. Compiled computer programs are typical examples; indeed, compiled applications are sometimes referred to, particularly by programmers, as binaries. But binary files can also mean that they contain images, sounds, compressed versions of other files, etc. – in short, any type of file content whatsoever. Some binary files contain ...

File Extension
A filename extension, file name extension or file extension is a suffix to the name of a computer file (e.g., .txt, .docx, .md). The extension indicates a characteristic of the file contents or its intended use. A filename extension is typically delimited from the rest of the filename with a full stop (period), but in some systems it is separated with spaces. Other extension formats include dashes and/or underscores on early versions of Linux and some versions of IBM AIX. Some file systems implement filename extensions as a feature of the file system itself and may limit the length and format of the extension, while others treat filename extensions as part of the filename without special distinction. Usage Filename extensions may be considered a type of metadata. They are commonly used to imply information about the way data might be stored in the file. The exact definition, giving the criteria for deciding what part of the file name is its extension, belongs to the rules of the ...

CD/DVD Copy Protection
CD/DVD copy protection is a blanket term for various methods of copy protection for CDs and DVDs. Such methods include DRM, CD-checks, Dummy Files, illegal tables of contents, over-sizing or over-burning the CD, physical errors and bad sectors. Many protection schemes rely on breaking compliance with CD and DVD standards, leading to playback problems on some devices. Protection schemes rely on ''distinctive features'' that: *can be applied to a medium during the manufacturing process, so that a protected medium is distinguishable from an unprotected one. *cannot be faked, copied, or retroactively applied to an unprotected medium using typical hardware and software. Technology Filesystems / Dummy files Most CD-ROMs use the ISO9660 file system to organize the available storage space for use by a computer or player. This has the effect of establishing directories (i.e., folders) and files within those directories. Usually, the filesystem is modified to use extensions intended to ...

CloneCD Control File
A CloneCD Control File is a text descriptor with the extension .ccd used by CloneCD to mark the properties of a CD/DVD image. These files need to be combined with an image file (usually with .img extension) to be burned. It may also come with a subchannel file (usually .sub). The .ccd extension can be used directly by first-party disc emulator Virtual CloneDrive. It can also be mounted with third-party virtual drives such as Daemon Tools and Alcohol 120%. The command line Linux application ccd2iso is available to convert ISO9660-compliant CCD/IMG files to an ISO image. The GNU Project's ccd2cue can convert a CCD file to a cue sheet. The CUE/BIN and MDS/MDF formats have a similar structure to the CCD/IMG format, containing both a raw disc image along with a descriptor file. The CloneCD CCD/IMG/SUB format is one of the few formats besides Nero's NRG, BIN/CUE and Alcohol 120%'s MDF/MDS disc image formats to support Mixed Mode CDs which contain audio CD tracks as well as da ...

NRG (file Format)
An NRG file is a proprietary optical disc image file format originally created by Nero AG for the Nero Burning ROM utilitIt is used to store Disk image, disc images. Other than Nero Burning ROM, however, a variety of software titles can use these image files. For example, Alcohol 120%, or Daemon Tools can mount NRG files onto virtual drives for reading. Contrary to popular belief, NRG files are not ISO images with a .nrg extension and a header attached. They can store audio tracks for Audio CDs, which ISO images cannot. Nero's NRG format is one of the few formats besides BIN/CUE, Alcohol 120%'s MDF/MDS and CloneCD's CCD/IMG/SUB disc image formats to support Mixed Mode CDs which contain audio CD tracks as well as data tracks. File format The file format specification below is unofficial and as such is lacking some data. There may also be errors. The NRG file format uses a variation of the Interchange File Format (IFF) and stores data in a chain of "chunks". All in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Text File
A text file (sometimes spelled textfile; an old alternative name is flatfile) is a kind of computer file that is structured as a sequence of lines of electronic text. A text file exists stored as data within a computer file system. In operating systems such as CP/M and MS-DOS, where the operating system does not keep track of the file size in bytes, the end of a text file is denoted by placing one or more special characters, known as an end-of-file marker, as padding after the last line in a text file. On modern operating systems such as Microsoft Windows and Unix-like systems, text files do not contain any special EOF character, because file systems on those operating systems keep track of the file size in bytes. Most text files need to have end-of-line delimiters, which are done in a few different ways depending on operating system. Some operating systems with record-orientated file systems may not use new line delimiters and will primarily store text files with lines separat ...

Nero Burning ROM
Nero Burning ROM, commonly called Nero, is an optical disc authoring program from Nero AG. The software is part of the Nero Multimedia Suite but is also available as a stand-alone product. It is used for burning and copying optical discs such as CDs, DVDs, Blu-rays. The program also supports label printing technologies LightScribe and LabelFlash and can be used to convert audio files into other audio formats. Name Nero Burning ROM is a pun in reference to Roman Emperor Nero, who was best known for his association in the Great Fire of Rome. The emperor allegedly fiddled while the city of Rome burned. Also, Rome in German is spelled Rom. The software's logo features a burning Colosseum, although this is an anachronism as it was not built until after Nero's death. Features Nero Burning ROM is only available for Microsoft Windows. A Linux-compatible version was available from 2005 to 2012, but it has since been discontinued. In newer versions, media can be added to compilations vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
