Physical File System


The FileManager control can work with a file system located on the server. To connect the control with the file system items, assign the Remote File System Provider to the fileSystemProvider property. Pass the endpointUrl to the remote file system provider object to specify the Url at which the control can access the file system items.

Configure the built-in server-side helper methods to process the FileManager control's AJAX requests on the ASP.NET MVC and ASP.NET Core back-end:

  1. Create an instance of the FileSystemConfiguration class to create a file system provider and configure its interaction with file system items.
  2. Use the FileSystemProvider property to specify a file system provider. For a physical file system, configure a file system provider of the PhysicalFileSystemProvider type.
  3. Use the FileSystemCommandProcessor class to process commands and request parameters that the control passes to the file system.

This demo contains commented out code lines that enable file modification operations. You can uncomment them and configure if necessary.
