Google's Matt Cutts: Don't Delete Old Disavow Files Before Uploading New Ones

Yesterday, Matt Cutts, Google's head spam fighter, posted on Twitter that you should not delete your old disavow file prior to uploading the new one.

He said on Twitter:

Quick SEO tip: no need to delete your old disavow links file before uploading a new one. You can just upload the new one.

Why? He clarified shortly after on Twitter:

Some SEOs have been deleting the file first, then uploading new, which creates two emails, and sometimes that confuses folks.

I am not sure exactly who it confuses? Probably the folks at Google who review disavow files for manual actions.

So I guess, just upload the new one that will replace the old file?
