Features

The cdrkit includes many features for CD and DVD writing, such as * creation of audio, data, and mixed (audio and data) CDs * burning CD-R, CD-RW, DVD-R. * usage without root identity is possible in many cases, some device drivers still may fail, show unexplainable problems * can use device node instead of

ID numbers on Linux * Creation of disc images with ISO9660, with optional Rock Ridge and Joliet extensions, and optionally with UDF 1.02 to support files beyond 4 GiB. * genisoimage can calculate the size of a disk image without having to create one, using the -print-size option. * Preservation of the last modified date and time attributes of files and folders, which can be seen in

). It automatically enables -udf. However, the correct sizes of files exceeding 4 GiB are only represented in the UDF file tree, not in ISO9660, therefore such files are only fully accessible while the file system is mounted as UDF. When mounted as ISO9660, only the first 4 GiB of any file that exceeds this size are accessible. The ISO9660 feature that would allow for exceeding the 4 GiB size limitation using multiple entries with the same file name has not yet been implemented. genisoimage is different from file archival utilities like

Front-ends

Other software can use cdrkit tools in the back-end. cdrkit tools will maintain interface compatibility with cdrtools 2.01.01a08 at least for the near future. Numerous programs can therefore use it, including the
