UDFtiedostojärjestelmän

UDFtiedostojärjestelmä, often abbreviated as UDF, is a file system designed for optical disc media such as CD-ROMs, DVD-ROMs, and Blu-ray discs. Its full name, Universal Disk Format, highlights its aim for broad compatibility across different operating systems and optical drive hardware. UDF was developed by the Optical Storage Technology Association (OSTA) as a successor to older file systems like ISO 9660, which had limitations in terms of file size, directory depth, and support for various data types.

One of the key advantages of UDF is its flexibility and extensibility. It supports larger file sizes and longer file names than its predecessors, making it suitable for storing large multimedia files like movies and software distributions. UDF also incorporates features for better error detection and recovery, which is crucial for optical media that can be susceptible to damage. It allows for both read-only and read/write operations, though its primary use case has historically been for distributing read-only content.

UDF is the standard file system for DVD-Video and DVD-Audio discs, ensuring that these discs can be played on a wide range of DVD players. It is also supported by most modern operating systems, including Windows, macOS, and Linux, allowing users to access and read data from UDF-formatted discs without requiring special software. While newer storage technologies have emerged, UDF remains a relevant and important file system for optical media distribution and archival.
