I don't know if there is official documentation on the format, but I think it would be theoretically possible to create compressed NWC files in a converter.
I see no point in reinventing the wheel.
Do you want such a converter? Here it comes:
Code: [Select · Download]
nwc2.exe -convert "%~dpn1.nwctxt" "%~dpn1.nwc"
Save it in a file and use the .bat extension.  ;)

For historical information, once upon a time there was a stand-alone file called "nwc-conv.exe" whose latest incarnation was version 2.5. Then it has been obsoleted and replaced by a simple command line parameter (see above).

None allowed me to select "save as type" other than .nwctxt, BUT the offered filename ended in .musicxml and saved as such.

However, when I tried to open the saved musicxml test files the ones from the two more recent versions would NOT import into Musescore while the older one did just fine.  Something is broken...
You made me wonder, so I investigated.
Well, in my case the file ended in "-nwctxt.musicxml.nwctxt" (maybe a bit verbose?  :) )
I peeked inside and it's a .musicxml.
And, in my case, once renamed, it opened perfectly in musescore.

N.B. Long long ago I had to explain to my daughter that "converting" from .doc to .txt, or from .jpg to .png is not simply a matter of changing the extension.  ;)

Lawrie, you missed the point.
I started with a .nwctxt file and, after the conversion,  my only option is to save it as  .nwctxt!   :o
I think I'm able to code myself such a converter.  :))
I need a file .musicxml or .mxl.
Sorry mate, I missed that little subtlety...
NWCCONVERTOR should do the conversion to MusicXML for you though - I've used it for exactly that in the past...

OK, just did some testing with Versions 2.0.05.04, 2.0.05.03 and 2.0.05.01

This is correct.  The compressed NWC file format is proprietary, which is a big part of why .nwctxt exists in the first place...  Or so I understand.
This was originally true; the native NWC format used to be a proprietary binary format, but at some point, the program changed to use gzip compression of the .nwctxt representation of the score, which came out to the approximate same size as the old native binary format. I don't know if there is official documentation on the format, but I think it would be theoretically possible to create compressed NWC files in a converter.

This does not answer Flurmy's concern over only being able to convert .nwctxt file to .nwctxt, but I thought I would respond with the historical information.

There is more.
I clicked "Select NWC txt file", loaded my file, selected the options, got "Conversion completed", clicked "Save as" and the only option is to save it... as .nwctxt!  :))

The culprit is:

N.B. After that, no way to go ahead with another file of whatever; olny exit and restart..
