Hello, I'm experimenting with porting my existing LabVIEW application from Windows to Mac OS X. The code uses several instances of 'Build Path' function in 'File I/O' functions sub-palette. The 'Name or Relative Path' input is being connected with a 'string' data type rather than a 'file path' data type. With some quick code change and checks, I've realized that it's better to use the latter data type, so that the separator character '\' in Windows is automatically interpreted as ':' in Mac OS. Some parts of the code, however, build up the string. E.g. a 'Format Into String' is used to output based on a format string, e.g. 'Images\%s.jpg'. Doing a 'String to Path' after this function does not automatically interpret the '\' in Mac OS to ':'. (I can imagine that it would be difficult for the compiler to recognize that a specific character is meant to be a separator and not part of a file/folder name.) I can write more complicated code where the format string is itself concatenated based on the execution platform. Are there any easier or recommended approaches? Also, does LabVIEW have any 'File Constant' that provides the equivalent string character depending on the platform? Thank you.
