Files

Access files on the PLC. Requires feature flag Files enabled.

Not implemented. File access requires the ADS SystemService protocol (index groups 0x78xx), which the underlying ADS library does not provide. All three endpoints below return 501 Not Implemented with error code NOT_IMPLEMENTED for every request. The routes are kept in place for API stability and will be implemented once the library gains SystemService support.
