I know that the two statements below are correct. However, Can somebody explained to me the difference ?. Thanks

1. Please find my resume attached.
2. Please find my attached resume.

1. Please find my resume [that has been] attached. OR

1a. Please find my resume [that I've] attached.

Here 'attached' is a past participle which is actually part of an ellipted phrase.

2. Please find my attached resume.

Here 'attached' is an adjective.
Hello Guest and M&M

I'm more used to reading 'Please find attached my XYZ' (or 'Please find enclosed').

This is the standard idiom in BrE. (I wouldn't know about AmE.)

Students: We have free audio pronunciation exercises.
Isn't there any difference in meaning?
Not that I can discern, M&M.
Teachers: We supply a list of EFL job vacancies
