by the DVD-RAM standard. However, for Windows up to 2000, DLA will also add support for DVD-RAM together with the UDF file system, for Windows XP DLA will only add the UDF support. DLA also supports the Mount Rainier standard with MRW capable drives. For Windows up to XP DLA will provide this functionality as well as the UDF support. Windows XP is the first Windows operating system to support DVD-RAM. Windows Vista is the first Windows operating system to support full UDF functionality (UDF up to version 2.50, full support meaning read and write operations) and Mount Rainier. Versions DLA is available only for Microsoft Windows operating systems and only in the English language. Version 4.95 runs on Windows 98SE, Me, NT 4.0, 2000 and XP. Version 5.21 is the most recent version for Windows 98SE, Me, 2000 and XP. Note: Most OEM versions officially support only Windows 2000 and XP; however, DLA itself also runs on older versions of Windows, like Windows 98 Second Edition and Windows Me, as well as Windows NT 4.0. A patch is required for Windows Vista compatibility, but it only works on the retail or trial version. The one exception is the Dell OEM version, but instead of patching DLA it will simply install Drag-to-Disc as a replacement. Known problems DLA is not compatible with Internet Explorer 8.
