SFTP: Configure and use custom filesystem adapter
By default TElSimpleSFTPClient creates an instance of TElDiskFileSystemAdapter and sets its BasePath property to the empty value. If you want to create a custom filesystem adapter or just have your own instance of the adapter being used (eg. SolFS adapter), you can assign it to the TElSimpleSFTPClient.FileSystemAdapter property.
