FS_FILEsFILEs) are grouped under file access (or simply file) functions. An application stores information in a file system by creating a file or appending new information to an existing file. At a later time, this information may be retrieved by reading the file. Other functions support these capabilities; for example, the application can move to a specified location in the file or query the file system to get information about the file.The entries within a directory can be traversed using the directory access (or simply directory) functions, which operate on directory objects (FS_DIRsDIRs). The name and properties of the entries are returned within a struct fs_dirent structure.anchor
