Subject: How to include some text and exclude other in one regular expression?

I would like to match "file 1 of 2" or "1 of 2", but not "day 1 of 2".

I can match "file 1 of 2" with...

	/(file)? *\d+ *of *\d+/

I wonder if (in the same regex), I can prevent a match to "day 1 of
2"?  The above expression will match this by just ignoring the word
"day".

Can this be done?

Thank you,
