"counter thesis"? Hooovahh explanation is correct. LV works on more than just one OS.

The "actual copy action" is always a system level command. Be it on Linux or Windows.

If you are restricting yourself to Windows, then Wiebe has the best answer... which I am now placing into my toolbox 👍

I read Hooovahh's post as " LabVIEW cannot cope with %TEMP% variable because it's multiplatform" and not as "you shouldn't use %TEMP% in LabVIEW because it might restrict you". That's why my counter thesis that it actually should be able to work with %TEMP%.

"Reading between the lines" is not required in this instance.

You are right that LabVIEW uses the Win32 API. But you are wrong that Windows knows on this level about environment variables. This is a feature of the Windows Shell (shell32.dll respective the Windows command prompt). Both of these use also the Win32 API underneath (and sometimes directly the Windows NT kernel API which lies under the Win32 API and should for all practical purposes still be considered undocumented).  The Windows kernel does not know about environment variables and not even about the registry. The Win32 API is nowadays a "fairly" thin layer around the Windows kernel API to maintain backward compatibility with the original Win3.1 API. But that didn't know environment variables either. That was a feature of the underlaying DOS, which was used to launch the DOS extender on which the Windows 3.1 GUI was then run.
