    The NFolder class contains properties and methods for working with folders in a platform independent way. In most cases you will work with one of the application Root Folders. When necessary you can also get a NFolder instance for a file system path, by using the GetFolder method of the NFileSystem class.

    The methods of the NFolder class are organized into two major categories:

     Folder and File Information

    The following methods of the NFolder class provide information about the files and folders contained inside a specific folder:

    Method Description
    NPromise<NFile[]> GetFilesAsync() Gets all files inside this folder.
    NPromise<NFile[]> GetFilesAsync(string searchPattern, ENFolderScanMode scanMode) Gets the child or descendant files that match the specified searchPattern.
    NPromise<NFolder[]> GetFoldersAsync() Gets all child folders of this folder.
    NPromise<NFolder[]> GetFoldersAsync(string searchPattern, ENFolderScanMode scanMode) Gets the child or descendant folders that match the specified searchPattern.
    NFile GetFile(string fileName) Gets a file, which is relative to this folder.
    NFolder GetFolder(string folderName) Gets a folder, which is relative to this folder.
           

    To get a file or a sub-folder of a given folder, it is recommended to use the GetFile and GetFolder methods respectively. For example, to get the file "MyFile.txt" from the folder "C:\Documents", you can use the following code:

    Get a file from folder
    Copy Code
    NFolder folder = NFileSystem.Current.GetFolder("C:\Documents");
    NFile file = folder.GetFile("MyFile.txt");
    
     Folder Manipulation and Information

    The following methods of the NFolder class help you manipulate folders, as well as obtain information about them.

    Method Description

    Folder Specific Operations

    NPromise<NUndefined> CreateAsync() Ensures that the folder is created.
    NPromise<NUndefined> EmptyAsync() Deletes all files and folders in the folder.
    NPromise<NFolder> CopyAsync(string destinationPath, bool overrideDestination) Copies this folder to the specified destination. If specified, overrides the duplicate descendant files and folders in the destination.
    NPromise<NFolder> MoveAsync(string destinationPath, bool overrideDestination) Moves this folder to the specified destination. If specified, overrides the duplicate descendant files and folders in the destination.

    Inherited from NFileSystemObject

    NPromise<NUndefined> DeleteAsync()  Deletes the folder
    NPromise<bool> ExistsAsync() Checks whether the folder exists.
    NFolder GetParentFolder() Get the folder in which the folder resides.
    NPromise<ENFileSystemObjectAttributes> GetAttributes() Gets the attributes of this file or directory.
    NPromise<NUndefined> SetAttributes(ENFileSystemObjectAttributes attributes) Sets the attributes of this file or directory.
    NPromise<DateTime> GetTime(ENFileSystemObjectTime time) Gets the specifies file system object time stamp.
    NPromise<NUndefined> SetTime(ENFileSystemObjectTime time, DateTime value) Sets the specifies file system object time stamp.
