==XDK and Xbox specific software limitations==
This is a list of XDK, Xbox hardware, and Xbox operating system specific limitations.

*[[Universal Disk Format|UDF (Universal Disk Format)]] file system limitation: The  Xbox only supports UDF version 1.02 (designed for [[DVD-Video]]), which has a maximum file size of 1&nbsp;[[Gigabyte|GB (Gigabyte)]] (a DVD in a newer UDF version with a video that is larger than 1GB will not play), with the same applying to UDF/ISO hybrid formats (a.k.a. UDF Bridge format). A workaround is to burn discs in the [[ISO 9660]] format. The ISO 9660 format has a 2&nbsp;GB maximum file size, which cannot be bypassed.<ref name="Modding The Xbox Into The Ultimate Multimedia Center"/>
*The Xbox hard disk is formatted in [[FATX|FATX (File Allocation Table for Xbox)]] which has a 4&nbsp;GB (4096 [[Megabyte]]) maximum file size, and only supports file/folder names up to 42 characters, a maximum of 255 character full path, and a maximum number of 4096 files/folders in a single folder, plus in the root of each partition, the maximum number of files/folders is 256. FATX also does not support all standard [[ASCII|ASCII characters]] in file/folder names (for example < > = ? : ; " * +, / \|¤ &).<ref name="Modding The Xbox Into The Ultimate Multimedia Center"/><ref name="Review of XBMC in Hardcore Gamer Magazine">{{cite web |title=Hardcore GamerĀ® Download |url=http://www.o-sd.com/hardcoregamermag/publicPDF/HGM_Aug.pdf |url-status=dead |archive-url=https://web.archive.org/web/20081118184719/http://www.o-sd.com/hardcoregamermag/publicPDF/HGM_Aug.pdf |archive-date=November 18, 2008 |access-date=May 31, 2010}} Review of XBMC in Hardcore Gamer Magazine</ref>
*The [[USB flash drive]] reader/writer [[Class (computer science)|class]] used by the Xbox operating system has a few limitations as well. It is limited to USB flash drives and [[hard disk]]s compatible with [[USB Mass Storage Device Class]] following the USB 1.1 standard, with a maximum size of 4&nbsp;GB. It can read and write to FATX formatted flash drives, but can only read FAT12, FAT16 (including VFAT), and FAT32. [[NTFS]] formatted drives are not supported yet.<ref name="Review of XBMC in Hardcore Gamer Magazine"/>
*With its 733&nbsp;MHz [[Intel Pentium III]]-like [[CPU]] and 64&nbsp;MB [[Shared memory (interprocess communication)|shared memory]], the Xbox has neither a fast enough CPU nor sufficient [[Random access memory|RAM]] to play [[HDTV]] videos encoded in native 720p/1080i resolution. However, the Xbox can upscale all [[SDTV|standard definition]] movies and output them at 720p or 1080i.<ref name="Modding The Xbox Into The Ultimate Multimedia Center"/><ref name="Review of XBMC in Hardcore Gamer Magazine"/>
