It is the appeal and strength of the iPhone that you can understand how to use it without reading the instructions.However, there are things that you know but do not understand correctly.In this corner, I will explain such "why an iPhone that I can't hear anymore" in an easy -to -understand manner.This time, answer the question, "Where is the" file "created in the app?"
***
The iPhone system (iOS) seems to be "not being aware of files" in the design policy.In the case of a personal computer, a list of files stored on an auxiliary storage device, such as a hard disk, determines the work target, but iOS is not as many as a personal computer.
In fact, the iPhone does not have a "shared data storage station that can be read and write from various apps" equivalent to a PC folder.There is a function to read and write files in areas on the Internet (cloud), such as iCloud, but the same thing cannot be performed with the built -in storage of the iPhone.Since it is not a difficult function on the iPhone, it should be seen as a design policy avoiding file management like a personal computer.
Documents and images created in the app are saved in the application area.This is because iOS adopts a structure called "sandbox" that manages various data independently for each app, enhancing security.As a result, saved data cannot be read or written directly from other apps, and there are no file browsers equivalent to Windows's "Explorer" or MacOS "Finder".
In this way, file management is performed for each app, so if you send files on your computer to the app, you will use the iTunes transfer function.Depending on the app, it is possible to transfer files wirelessly using the function of "AirDrop" from the Mac, or pass the data/file to other apps using a shared menu, but all apps are possible.is not.
In addition, some data/files such as images (photos) and music are allowed to access directly from different apps.Even in that case, when you use it for the first time, you will not be able to access dialogs such as "XXx is looking for access to △△△" and will not be accessed unless you have permission by the user.
Since the file is independent for each application, the target application must be identified and transferred when sent from the computer. |
