The Library
directories are where the system and your code store all of their related data and resources. In macOS, this directory can contain many different subdirectories, most of which are created automatically by the system. In iOS, the app installer creates only a few subdirectories in ~/Library
(such as Caches
and Preferences
) and your app is responsible for creating all others.
Table A-1 lists some of the common subdirectories you might find in a Library
directory in macOS along with the types of files that belong there. You should always use these directories for their intended purposes. For information about the directories your app should be using the most, see The Library Directory Stores App-Specific Files.
C Library Max Function
The C library is needed by essentially all Linux applications, CrossOver programs included. No Windows application can run without it. No Windows application can run without it. Because it is so important only the 32-bit version of this library can ever be missing and only on 64-bit machines since those often don't have any 32-bit application.
Subdirectory | Directory contents |
---|---|
| Contains all app-specific data and support files. These are the files that your app creates and manages on behalf of the user and can include files that contain user data. By convention, all of these items should be put in a subdirectory whose name matches the bundle identifier of the app. For example, if your app is named MyApp and has the bundle identifier Resources required by the app to run must be placed inside the app bundle itself. |
| Contains programs that assist users in configuration or other tasks. |
| Contains audio plug-ins, loops, and device drivers. |
| Contains app-specific autosave data. |
| Contains cached data that can be regenerated as needed. Apps should never rely on the existence of cache files. Cache files should be placed in a directory whose name matches the bundle identifier of the app. By convention, apps should store cache files in a subdirectory whose name matches the bundle identifier of the app. For example, if your app is named MyApp and has the bundle identifier |
