내가 uses the subject marker -가, which puts focus on I as the person who did the recording.

In this sentence, 내가 녹음한 파일 means the file that I recorded, so 내가 helps identify who recorded the file.

Comparison:

• 내가 녹음한 파일 = the file that I recorded
• 나는 녹음한 파일 sounds unnatural here, because 는 is for topic marking, not the best choice inside this kind of modifying clause
• 제가 녹음한 파일 would be a more polite version

So 내가 is natural in casual speech, especially when you are simply specifying which file.

녹음한 is the verb 녹음하다 (to record) changed into a form that modifies a noun.

So:

• 녹음하다 = to record
• 녹음한 = recorded / that I recorded

This is a very common Korean structure:

• 내가 녹음한 파일 = the file that I recorded
• literally, I-recorded file

Korean often puts noun-modifying verb forms before the noun, where English would often use that/who/which.

More examples:

• 제가 만든 음식 = the food that I made
• 어제 본 영화 = the movie I watched yesterday

Because Korean usually does not need a separate relative pronoun like that, which, or who.

Instead, the verb changes form and directly modifies the noun:

• 내가 녹음한 파일
• literally: I recorded file
• natural English: the file that I recorded

This is one of the biggest structural differences between English and Korean.

So when English says:

• the book that I bought Korean says:
• 내가 산 책
• literally: I bought book

편집해서 comes from 편집하다, which means to edit.

The ending -해서 connects actions and often means:

• and then
• by doing
• sometimes because

Here it means sequence:

• 편집해서 = edit it and then...

So the sentence flow is:

1. edit the recorded file
2. send it back to the teacher

In natural English:

• I’ll edit the file I recorded and send it back to the teacher.

Here it most naturally means and then / after doing that.

So:

• 편집해서 선생님께 다시 보낼게 means
• I’ll edit it and send it back to the teacher or
• After editing it, I’ll send it back to the teacher

It does not really mean because in this sentence.

A useful way to think about -아서/어서 is that it often links actions in a smooth sequence:

• 밥을 먹어서 갔어요 can sound like I ate and then went
• 파일을 편집해서 보낼게요 = I’ll edit the file and send it

께 is an honorific dative marker, used when the receiver is someone deserving respect.

Since 선생님 means teacher, using 께 shows politeness and respect.

Comparison:

• 선생님께 = to the teacher, respectful
• 선생님에게 = also possible, but less honorific
• 선생님한테 = more casual, less formal

Because the sentence involves sending something to a teacher, 께 is a very natural choice.

Here 다시 can feel like again or back, depending on context.

In this sentence, 다시 보낼게 most naturally means:

• I’ll send it again or
• I’ll send it back

The intended meaning is probably that the speaker already sent something before, or is now sending a revised version.

So in context:

• 다시 = again / back / once more

Korean 다시 often covers both ideas, and English chooses the most natural translation from context.

보낼게 is from 보내다 (to send) plus -ㄹ게.

-ㄹ게 / -을게 usually expresses:

• the speaker’s intention
• a decision made now
• a promise or assurance to the listener

So 보낼게 is not just plain future. It feels more like:

• I’ll send it
• I’ll send it, okay
• I’ll make sure to send it

It is commonly used when speaking directly to someone and letting them know what you will do.

Comparison:

• 보낼게 = I’ll send it / I promise I’ll send it
• 보낼 거예요 = I’m going to send it / I will send it
• 보내겠습니다 = I will send it, very formal

Yes. The sentence mixes:

• a casual ending: 보낼게
• with a respectful noun/particle choice: 선생님께

That is completely possible in Korean.

It means the speaker is talking in a relatively casual or semi-casual way, but still showing respect toward the teacher as the recipient of the action.

If the whole sentence were made more polite, it could be:

• 제가 녹음한 파일을 편집해서 선생님께 다시 보낼게요. or more formal:
• 제가 녹음한 파일을 편집해서 선생님께 다시 보내겠습니다.

파일을 has the object marker -을, because 파일 is the thing being edited and sent.

In Korean, the object marker shows what the verb acts on.

Here:

• 내가 녹음한 파일을 = the file that I recorded as the object
• that file is what gets edited
• and it is also understood as what gets sent

So 파일을 is the main object for the connected action sequence.

Yes, in a way.

The sentence only says 파일을 once, but that object carries over naturally to the later verb:

• 내가 녹음한 파일을 편집해서 선생님께 다시 보낼게
• literally: I’ll edit the file I recorded and send it back to the teacher

Korean often omits repeated words when they are already clear.

So even though there is no second 파일을, it is understood:

• [파일을] 편집해서 [파일을] 선생님께 다시 보낼게

This is very normal and natural in Korean.

Yes, that is a good close translation.

A more natural English version might be:

• I’ll edit the file I recorded and send it back to the teacher.
• I’ll edit the recording and send it to the teacher again.

The best English version depends on context:

• if the focus is the actual file, file is good
• if the focus is the audio content, English might prefer recording

But grammatically, the file I recorded is a correct understanding of the Korean structure.
