[Grammar] We will send the

[suniljain]

We will send the documents file tomorrow morning at your office.

Is this correct? Should I use "at" or any other preposition is better?

 

[tedmc]

We will send the document file to your office tomorrow morning.

 

[suniljain]

We will send the document file to your office tomorrow morning.

Does it mean my original construction is not correct?

 

[tedmc]

1. You say document file, file of documents, documents, not documents file.

2 You don't send something at somebody's office. You send something to somebody/somewhere.

3. Don't you think the sentence is better if you put tomorrow morning at the end instead of in the middle?
