UDF [Files]

  • Article

The Universal Disk Format (UDF) is defined by the Optical Storage Technology Association (OSTA). It is designed to replace CDFS and add support for DVD-ROM. UDF is included in the DVD specification and is more flexible than CDFS. Support for UDF was introduced in Windows 2000. The file system implementation is compliant with ISO 13346 and supports UDF versions 1.02 and 1.5.

The UDF file system has the following traits:

  • File names can be 255 characters long.
  • File names can be uppercase and lowercase.
  • The maximum path length is 1023 characters.

**Windows 2000:  **The UDF implementation was designed with rewritable media in mind but includes only read-only support. Starting with Windows XP, there is read and write support.
