Bundle (macOS)
open-in-new
<p>In <a href="/facts/NeXTSTEP/eL0bymga">NeXTSTEP</a>, <a href="/facts/OPENSTEP/RTKQxPR1">OPENSTEP</a>, and their lineal descendants <a href="/facts/MacOS/Y93vVpTm">macOS</a>, <a href="/facts/IOS/mK5cggH5">iOS</a>, <a href="/facts/IPadOS/fClrmH7D">iPadOS</a>, <a href="/facts/TvOS/jDMqvvfI">tvOS</a>, <a href="/facts/WatchOS/zH1fkn2R">watchOS</a>, and <a href="/facts/VisionOS/2Igexrxe">visionOS</a>, and in <a href="/facts/GNUstep/LaIT4jYx">GNUstep</a>, a bundle is a file <a href="/facts/Directory_(file_systems)/VLtLcEXY">directory</a> with a defined structure and file extension, allowing related files to be grouped together as a conceptually single item. </p><p>Examples of bundles that contain executable code include <a href="/facts/Application_software/YQuj7Kog">applications</a>, <a href="/facts/Application_framework/xSzKMgdn">frameworks</a>, and <a href="/facts/Plug-in_(computing)/351Du3Wu">plugins</a>. This kind of bundle usually contains one file representing executable code, and files that represent resources such as <a href="/facts/Interface_Builder/IMK6EyVq">nibs</a>, templates, images, sounds, and other media. On some other systems, such as <a href="/facts/Microsoft_Windows/bwhAhuSL">Microsoft Windows</a>, these resources are usually included directly in the executable file itself at compile time. On older Macintoshes, a similar technique is used, where additional <a href="/facts/Metadata/qt35z79C">metadata</a> can be added to a file's <a href="/facts/Resource_fork/zVnSVjbb">resource fork</a>. Similar in concept are the <a href="/facts/Application_Directory/2Kgfpzeh">application directories</a> used in <a href="/facts/RISC_OS/Pc96teso">RISC OS</a> and on the <a href="/facts/ROX_Desktop/BVU1huet">ROX Desktop</a>. </p><p>Examples of bundles that do not contain executable code include document packages (<a href="/facts/IWork/n37Q7Wqm">iWork</a> documents) and media libraries (<a href="/facts/IPhoto/NdaTrBRv">iPhoto</a> Library). </p><p>Bundles are programmatically accessed with the NSBundle class in <a href="/facts/Cocoa_(API)/p10p5aFI">Cocoa</a>, NeXTSTEP and GNUstep's <a href="/facts/Foundation_Kit/LcnWzx5R">Foundation</a> frameworks, and with CFBundle in <a href="/facts/Core_Foundation/mWDmymXU">Core Foundation</a>. Bundles often include an Info.<a href="/facts/Property_list/tlRqjIvP">plist</a> file for metadata. The <a href="/facts/Uniform_Type_Identifier/RX7PIbn0">Uniform Type Identifier</a> (UTI) for an Apple bundle is com.apple.bundle. </p>
