Universal Disk Format (UDF): The UDF file system is an installable file system that is used on DVDs and CDROMs. UDF allows A package called DirectCD to write/delete single files to/from CDs/DVDs. It can handle very large disks (e.g. DVDs). UDF, unlike the older ISO9660, can maintain Macintosh file attributes within the UDF file system. UDF 1.02 is available in Windows98/WindowsNT. A later (backward compatible) version UDF 1.15 is available from Adeptec. UDF 1.15 supports CD-R and CD-RW. Adaptec UDF readers purportedly allow UDF formatted CD-ROMs written in CD-R or CD-RW drives to be read in "Multi-Read" CD-ROM drives
