Note that if the cRIO is formatted, the INI token will have to be added again.
This issue is specific to LabVIEW Real-Time 2017 and the corresponding NI Linux Real-Time version for NI Linux Real-Time Intel x64 targets. R&D is already aware of the issue and this bug will be addressed in a future release.
Using FTP to access files on cRIO is a deprecated method and is not recommended. WebDAV is the recommended replacement. WebDAV LabVIEW VIs
exist to manipulate files programmatically.
