write to measurement file - Create or replace with confirmation

[SuSto]

The question probably is too basic, as I'm very new to LabVIEW. Basically, I tried to use "Open/Create/Replace File" to set my file path, but it doesn't have an output file path to wire into the "Write to measurement file express vi". I'm wondering if there is any way to make a file path with "create or replace with confirmation" settings (without creating an actual file yet), and then use that as the file path for the "Write to measurement file express vi".

Surely there is a better way, but here is what you can do based on your question.  It seems redundant, but modify as needed.

Any Express VI can be converted to a regular VI by right-clicking on it and selecting "Open Front Panel". Yeah, I know, not very intuitive. You'll get a warning about it. Once you acknowledge you'll get a new VI which is a shell around another subVI, which is the actual meat of the Express VI. You can then modify the new VIs. When I do this I typically toss out the first-level VI since it's just a wrapper.

There's a Refnum to Path function in the File I/O -> Advanced palette.   EDIT: I see that Mo already provided the answer while I was entering my reply.

I assume you mean you want another channel of data. If so, just merge the new signal with your other one. Use the Merge Signals on the Signal Manipulation palette. The two signals will be written as two channels in your measurement file.
