NQC programs run on the RCX which has no disk drive to write to, hence no file
system or commands to do so. You might want to look at the Data Log feature of
the RCX, which allows you to save data points (up to about 6,000 of them) such
as sensor readings or variable values into a special memory area in the RCX.
The contents of the Data Log can be uploaded to the PC and saved into a text
file after the fact. NQC has native commands to support Data Logging.
I had written a small program at one point to upload the RCX Data Log, and if I
can find it and dust it off I will make it available on my web site. (Contact
me by e-mail if you are desperate to get this program ahead of my lazy
schedule.) I believe that other tools exist for uploading the Data Log, but I
have not used them and cannot speak for them.
Hope this helps!

p.s. I am still getting lots of "Your message was not accepted. Response from
the news server: 0" messages when I try to post, although it eventually works
after about 40 or 50 tries. <sigh> Do you remember when being a "hacker" was a
Good Thing?
