Answer 1

The Universal Disk Format (UDF) is a format specification of a file system for storing files on optical media. It is an implementation of the ISO/IEC 13346 standard (also known as ECMA-167). It is considered to be a replacement of ISO 9660, and today is widely used for (re)writable optical media. UDF is developed and maintained by the Optical Storage Technology Association (OSTA)

media use UDF version 1.02. These discs contain a so-called UDF Bridge format, where both an ISO 9660 as well as a UDF 1.02 filesystem are present on the same disc, describing the same filesystem.

All standard formats for video recording on DVD-style media use some version of the UDF filesystem.

* Philips' DVD+VR format uses UDF 1.02 with an ISO 9660 bridge for DVD+R and DVD+RW.
* The DVD Forum's DVD-VR format uses UDF 2.00 for DVD-R, DVD-RW and DVD-RAM.
* Blu-ray and the DVD Forum's HD-DVD will be using UDF 2.50 or UDF 2.60.
* Hyper Scan game console uses a version of UDF for the game data

When combined with packet writing technology, UDF has the advantage of allowing files to be added to and removed from a disc through the normal filesystem mechanisms. That is, the contents of a disc can be manipulated in the same way a hard disk, floppy disk, or USB flash drive might be. This even works for sequentially written media such as CD-R, although files that are deleted remain on the disc occupying space. In Windows the disc appears as a drive letter, while in Unix/Linux or Mac OS X it is mounted to a directory.

Typically for writing UDF in Windows, third-party burner software such as DirectCD, DLA, InCD, Toast, and WriteUDF is required. As shipped by Microsoft, Windows (before Windows Vista) can only read UDF discs, while current (2006) releases of Mac OS X, Linux, and several other Unixes include UDF writing capability with no additional software required. Older versions of these operating systems may have limited reading capabilities, and may not support more recent versions of UDF. See the table below for more detailed information.

Answer 3

Universal Disc Format. A file system endorsed by OSTA (the Optical Storage Technology Association) for use with packet writing and other recordable optical disc technologies, such as DVD. UPC Universal Product Code. With some CD recorders, you may define a thirteen-digit UPC catalog number for the entire disc, which will be written in the disc's Table of Contents. Also known as EAN.

Answer 4

it somewhat is a variety of CD image document. It acts a similar way a zipper document does. fairly than copying each and every document on your no longer common stress, it condenses the DVD or CD right into a picture document that during basic terms DVD/CD burning classes can examine. in many situations, Microsoft's burning utility is for burning individual data. you will desire a third social gathering application for burning CD image data like an ISO. An ISO document is in all probability the main commonly used variety of CD image document. there is likewise a company referred to as ISO that stands for international business enterprise for Standardization. i understand the accronym isn't interior the final order. they're a employer that develops many distinctive standards. For computers, they progressed the OSI form. there is yet another ISO that refers to pictures.

Udf 2.50
