How to develop your own file system backend

Main steps

• Implement IFileSystemClassFactory
  • This allows a custom instantiation of a IUnixFileSystem depending on the user credentials
• Implement IUnixFileSystem
  • Everything that's not supported by your backend should throw an exception
  • When a specific command isn't supported, then you should provide the supported command handlers to the FtpServer constructor
• The IUnixFileSystemEntry is the base for both file and directory entries
• The implementation of IUnixFileEntry should inherit from your IUnixFileSystemEntry implementation
• The implementation of IUnixDirectoryEntry should inherit from your IUnixFileSystemEntry implementation
• When you don't support access permissions, you should use GenericUnixPermissions together with GenericAccessMode (for user, group, other) with rwx for directories and rw for files
