Recommended Tools
WinSCP and Visual Studio Code (VS Code) are recommended for connecting to and editing, respectively, remote Flex configuration files. You can browse remote files in WinSCP's Explorer‑like interface, open them with VS Code, and any changes you make will be saved to the remote system.
Note: You can set VS Code as your default editor in WinSCP preferences; then double-clicking a file will open it in VS Code.
