For Windows, according to [MS](https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=cmd), MAX_PATH = 260 (includes zero terminator).  Longer paths (up to 32767) can be used if certain path prefixes (`\\?\`) are used.  For Win10, long paths can also be enabled with a registry key.  The app must have a manifest file and it applies to only some functions.
