attached or attachment

please correct me when I send a email with attachment:

“please see attached file” or “please see attachment”

or " more information as attached file"

thanks in advance

The first two seem all right to me, both would be acceptable. The third choice I would change to

  • more information in attached file

I think you can choose among: ‘please see\refer to the attachment\attached file’, ‘see’ sounding informal here.

Or I prefer Kindly attached find…

You mean “Please kindly find attached…”?
Personally, I like the way they look at that business jargon:

“There are multiple arguments against using the phrase “please find attached” or the alternative “attached please find” in an email message.
First of all, the literal meaning is bizarre: You are imploring the reader to go search for an attachment that is sitting there conspicuously, right in front of his face.
Second, it is an awkward and unnatural-sounding construction. If you can’t imagine walking up to someone at work with a pile of papers and saying, “Enclosed please find the report you requested,” it’s not a phrasing you should use in your email.

Instead of using the clunky “please find attached,” just write “I have attached…” or “Attached is…”

With this adjustment, the wording of your opening sentence will still be 100 percent professional, but the language will sound more natural, more comfortable, and more confident. You will be writing in your own skin.

This structure does not sound as meaningful as you think. ‘Attached please find’ or ‘Please find attached’ is a phrase often found in formal communications. The reason for using the former is to draw the attention of the reader to the attachment first and that for the latter is to show the courtesy/politeness first. The word ‘find’ does not seem to collocate well here, though.

In modern English, changes are inevitable. We can see sentences like ‘Here is the attachment that contains the document you have called for’ and ‘The attachment contains the document that you have called for’ appear in formal or business letters.

In any case, ‘Please kindly find attached’ is too officious and redundant. In a democratic set up such usages are rather outdated and ‘unstylistic’.

Thank you so much indeed from both of you guys.
Your viewpoints are really helpful.
