는 is the topic particle. It marks 그녀 as the topic of the sentence: as for her...

So 그녀는 means something like:

• she
• as for her

In many contexts, Korean drops subjects if they are already understood, so 그녀는 is often included only when the speaker wants to make the subject clear or emphasize it.

출장 중에도 can be broken down like this:

• 출장 = business trip
• 중 = in the middle of, during
• 에 = a particle often used with time/state expressions here
• 도 = also, even

So 출장 중에도 means:

• even during a business trip
• while she was on a business trip too
• more naturally, even while she was away on business

The important nuance of 도 here is even or despite that situation.

중에 means during or in the middle of.

Adding 도 gives 중에도, which adds the idea of:

• also
• even
• despite being in that situation

Compare:

• 출장 중에 = during a business trip
• 출장 중에도 = even during a business trip

So the sentence suggests that she downloaded the file despite being busy or away on business.

클릭해서 comes from:

• 클릭하다 = to click
• 해서 = the connective form of 하다

Here -해서 links two actions:

• clicking the link
• downloading the file

So it means:

• clicked the link and downloaded...
• by clicking the link, she downloaded...

In this sentence, -해서 shows that the first action leads into the second action.

Here it mainly connects actions in sequence or shows means:

• She clicked the link and downloaded the necessary file
• She downloaded the necessary file by clicking the link

Although -아서/어서 can sometimes mean because, in this sentence the most natural reading is action 1 leading to action 2, not really because.

So this is closer to:

• click the link, then download the file than
• because she clicked the link...

필요한 is the modifier form of 필요하다 (to be necessary / needed).

In Korean, verbs and adjectives can directly modify nouns. So:

• 필요하다 = to be necessary
• 필요한 파일 = a necessary file / the file that is needed

This is similar to saying:

• the needed file
• the necessary file

So 필요한 파일을 means the necessary file as the object of the sentence.

다운로드하다 is a very common Korean verb based on the English word download plus 하다.

So:

• 다운로드하다 = to download
• 다운로드했어요 = downloaded

Korean often uses these loanword + 하다 verbs in technology-related contexts.

You may also hear more native-style expressions like:

• 내려받다
• 다운받다

But 다운로드하다 is perfectly natural and common.

다운로드했어요 is:

• past tense
• polite speech

Breakdown:

• 다운로드하다 = to download
• 했어요 = did / did it (polite past of 하다)

So the sentence ends politely, in the everyday -어요/-아요 style.

It is polite but not formal in the highest sense. A more formal version would be:

• 다운로드했습니다

을/를 marks the direct object of the verb.

Here there are two objects because there are two verb actions:

• 링크를 클릭해서 = clicked the link
• 파일을 다운로드했어요 = downloaded the file

So:

• 링크를 goes with 클릭해서
• 파일을 goes with 다운로드했어요

This is very normal in Korean when one clause leads into another.

Yes. Korean word order is usually Subject-Object-Verb, and modifiers come before the noun.

This sentence is roughly structured like:

• 그녀는 = she / as for her
• 출장 중에도 = even during a business trip
• 링크를 클릭해서 = clicking the link / after clicking the link
• 필요한 파일을 = the necessary file
• 다운로드했어요 = downloaded

So the verb comes at the end, which is one of the biggest differences from English.

Yes, very often.

If the subject is already clear from context, Korean usually leaves it out. So a very natural version could simply be:

• 출장 중에도 링크를 클릭해서 필요한 파일을 다운로드했어요.

The meaning would still be understood if everyone knows who is being talked about.

Using 그녀는 makes the subject explicit, but in everyday Korean, repeated pronouns like she are much less common than in English.

중 is a dependent noun, so it is commonly spaced separately after the noun it follows:

• 출장 중 = in the middle of a business trip / on a business trip

Then particles attach to 중:

• 출장 중에
• 출장 중에도

So the spacing in the sentence is normal standard Korean writing.

Yes. 출장 중에도 does not specify a precise moment. It just means during the period of the business trip.

So it could mean she did it:

• while traveling
• while staying somewhere for work
• at some point during the trip

The expression describes the general situation, not an exact timestamp.

The sentence suggests a little more than just a neutral fact. Because of 도, it implies something like:

• even though she was on a business trip
• despite being away on work
• she still managed to do it

So there is a slight sense that downloading the file was notable, responsible, or done in less-than-ideal circumstances.
