Hi!

Is there any IRP? ? when copy operation is performed
either on content of file or file itself.

Actually yes… There ARE ( not IS ) IRP when you do a copy operation!
Multiple IRPs come.
As such there is NO single IRP for COPY operation.

Consider searching the archives before posting! This has been asked sooooooooooooooooooooo many times.

No, and as Ayush said its already been discussed a lot of times, So please search for archives, in fact this is being discussed few weeks back only,

>when copy operation is performed either on content of file or file itself.

What do you mean by “on content or file”.

you open and read src file, you create and write destination file, that is it. nothing special.

No.

On source file: create-read-read-read-cleanup-close
On destination file: create-write-write-write-cleanup-close

As you may have noticed kernel mode operations handle only the basics of
complex operations such moving/copying.
I have see a lot of questions like this one, and questions like what happens
in the kernel when I select something in explorer, etc…
You should make a little abstraction of what it happening in the users space
against what is happening in kernel.
Like the CopyFile api, as maxim stated, it is clearly that it is implemented
also with basic operations of Read/Write. You cannot possibly detect if the
CopyFile api was called or if someone is just doing I/O on a file, so try
designing you code, in such a manner that it will not depend on the
“complex” operations happening in user space, but on the “basic” ones that
take place in the kernel.
