With file name length I do refer to the total length of the path actually and the limit there is as I have said 259 characters This is a Windows API limitation and can only be overcome with quite some humbo bumbo using Unicode API functions and special path name syntax with an added \\?\ before the actual file name. As it seems to turn out at least some of the LabVIEW functions do have a limit of 128 character for each hierarchy level in a path. This is not entirely logical as the hierarchy level elements are stored as a short Pascal string internally which would be able to handle 255 chars and LabVIEW does that in most places actually. It may be however possible that in the function to convert a LabVIEW path into a platform path sring, there might be a small bug using a signed char at some place during the conversion for the lenght of such an element. It shouldn't be a serious problem in most cases as the path itself is limited to 259 characters on Windows anyhow.
