the Media Transfer Protocol for transferring media content from portable devices. Thus, for digital cameras, Windows XP supports acquiring photos using any of either WIA, PTP, USB Mass Storage Class or MTP protocols depending on what the camera manufacturer supports. CD burning Windows XP includes technology from Roxio which allows users to directly burn files to a compact disc through Windows Explorer. Previously, end users had to install CD burning software. In Windows XP, CD and DVD-RAM (FAT32 only for DVD-RAM) burning has been directly integrated into the Windows interface. Data discs are created using the Joliet and ISO 9660 file systems and audio CDs using the Redbook standard. To prevent buffer underrun errors, Windows XP premasters a complete image of files to be burnt and then streams it to the disc burner. Users can burn files to a CD in the same way they write files to a floppy disk or to the hard drive via standard copy-paste or drag and drop methods. The burning functionality is also exposed as an API called the Image Mastering API. Windows XP's CD burning support does not do disk-to-disk copying or disk images, although the API can be used programmatically to do these tasks. Creation of audio CDs is integrated into Windows Media Player. Audio CDs are burnt using track-at-once mode. CD-RW discs can be quick erased. API support can be added to Windows XP for burning DVDs and Blu-ray Discs (Mastered-style burning and UDF) on write-once and rewritable DVD and Blu-ray media by installing the Windows Feature Pack for Storage which upgrades IMAPI to version 2. Note that this does not add DVD or Blu-ray burning features to Windows Explorer but third-party applications can use the APIs to support DVD and Blu-ray burning.
