with regards to or with regard to and more

Hi to all,
Kindly explain to me which one is correct. I've seen people use both of them in their writings.

Another thing is that, if a friend send you an email with more than one files attached, should we say" Attached is the file for your perusal" or "Attached are the files for your perusal"

regards,

I'd use 'regard' and if sending files, I'd use a plural verb.

Hi and thanks for your very short and concise explanation.
One more thing, can I write " Please refer to the attached files" or "Please refer to the attachments" or "Please refer to the files attached"

Yes, any of those.
