  You can exclude files by pattern or by any pattern from file.
From `diff --help`:
...
  -x PAT  --exclude=PAT  Exclude files that match PAT.
  -X FILE  --exclude-from=FILE  Exclude files that match any pattern in FILE.
...

and quote pattern with "".  Read also `info.exe diff "invoking diff"'.

But, IMHO, better is to remove all unwanted files before comparing.
