Inside /, you'd look for var and click it, and so on, until you got to temp.file. If you were navigating this file structure in a graphical user interface, you would next find the usr folder and click it. The path starts at the root folder, which on UNIXlike systems is represented by a forward slash. Referring to the Linux structure shown in Figure 4.9, consider the following path: The path is the path you have to take from the root folder to get to the individual file. You refer to a specific folder or file by its path. Momentarily I will show you how all these folders are supposed to be used, but for now, it's important to see that all three are organized into trees. Figures 4.7, 4.8 and 4.9 show the basic structure for each platform:įigure 4.8. All three platforms organize their folders and files in a different way. At the root of the tree is the volumetypically a hard drive or some other storage deviceand this volume can contain folders or files of different types. Referencing a FolderItem: Paths and URLsįolders and files are organized into hierarchical trees. Depending on which platform you first learned about computers, you may use the term directory instead of folders I happen to use the two terms interchangeably.Īlthough folders and files may seem like entirely different things to you, they have a lot in commonhence, a single class to represent both. FolderItem ClassĪ FolderItem is a reference to both folders and files. When compiling for Carbon, filenames are limited to 31 characters. The extension is also no longer limited to three characters. You do not necessarily have to use extensions on other files, but REALbasic uses file extensions to detect file types, so my advice is to use them.

NTFS and HFS Plus are the two default file systems on Windows and Macintosh OS X, respectively. Windows, Macintosh, and Linux File Systems Table 4.1 documents the file systems in use on the three platforms: In this section I will review the FolderItem class and how it interacts with the underlying operating system then I'll cover how each operating system organizes its files. Additionally, each platform uses a different file system with different requirements. Each platform has standards for where applications, documents, preference files, and so on should be stored. The way in which the folders and files are organized in each platform vary greatly. Because one of the properties you are asked to identify refers to the kind of file types your application will be handling, this is a good point to introduce how REALbasic handles documents and folders and discuss the cross-platform implications of it all.
