For information about creating a UDFS file system on removable media, see How to Create a File System on Removable Media.
The UDF file system is provided as dynamically loadable 32-bit and 64-bit modules, with system administration utilities for creating, mounting, and checking the file system on both SPARC and x86 platforms. The Solaris UDF file system works with supported ATAPI and SCSI DVD drives, CD-ROM devices, and disk and diskette drives. In addition, the Solaris UDF file system is fully compliant with the UDF 1.50 specification.
The UDF file system provides the following features:
Ability to access the industry-standard CD-ROM and DVD-ROM media when they contain a UDF file system
Flexibility in exchanging information across platforms and operating systems
The following features are not included in the UDF file system:
Support for write-once media, (CD-RW), with either the sequential disk-at-once recording and incremental recording
UFS components such as quotas, ACLs, transaction logging, file system locking, and file system threads, which are not part of the UDF 1.50 specification
The UDF file system requires the following:
At least the Solaris 7 11/99 release
Supported SPARC or x86 platform
Supported CD-ROM or DVD-ROM device
The Solaris UDF file system implementation provides the following:
Support for industry-standard read/write UDF version 1.50
Fully internationalized file system utilities
