miti ni mayowanai you ni, tizu no gamen wo sukuriinsyottosite okimasu.

It means so that I won’t get lost or in order not to get lost.

Breakdown:

• 迷わない = the negative form of 迷う (to get lost)
• ように = so that, in order to, with the aim that

So:

• 道に迷わないように = so that I don’t lose my way

This pattern is very common:

• 忘れないようにメモします。
  I’ll write a note so that I don’t forget.
• 遅れないように早く出ます。
  I’ll leave early so that I won’t be late.

Because the speaker’s goal is to avoid getting lost.

• 迷う = to get lost
• 迷わない = to not get lost

So the sentence is not saying in order to get lost; it is saying in order not to get lost.

This is very natural in Japanese. A negative verb before ように often expresses prevention:

• 風邪をひかないように = so that I won’t catch a cold
• 忘れないように = so that I won’t forget

In 道に迷う, the に is part of the standard expression 道に迷う, which means to lose one’s way.

A native English speaker may expect something like the road to be a direct object, but Japanese uses a different structure here. You should learn 道に迷う as a set phrase.

• 道に迷う = to get lost / lose one’s way

The に here is not the same as the purpose に in ように later in the sentence.

They are doing different jobs:

1. 道に迷う
   Here, に belongs to the expression 道に迷う.

2. 迷わないように
   Here, に comes after よう and completes the grammar pattern V-plain + ように, meaning so that / in order to.

So even though you see に twice close together, they are not the same grammatical element.

It means more than just take a screenshot. The 〜ておきます part adds the nuance of doing something in advance or doing something and leaving it ready for later.

So:

• スクリーンショットします = I’ll take a screenshot
• スクリーンショットしておきます = I’ll take a screenshot beforehand / I’ll save a screenshot in advance

In this sentence, that nuance matters a lot:

• 道に迷わないように、スクリーンショットしておきます。
  I’ll take a screenshot in advance so I won’t get lost.

It suggests preparation for a future situation.

〜ておく often means one of these:

• do something in preparation
• do something beforehand
• leave something as it is

In this sentence, it is the preparation meaning.

Structure:

• スクリーンショットして = take a screenshot
• おきます = do it in advance / keep it done

Other examples:

• 後で読むために、保存しておきます。
  I’ll save it so I can read it later.
• 旅行の前に、ホテルを予約しておきます。
  I’ll reserve the hotel in advance before the trip.

Yes. In Japanese, many loanwords can function as suru-verbs.

So:

• スクリーンショットする = to take a screenshot
• スクリーンショットして = taking a screenshot / and take a screenshot
• スクリーンショットしておきます = I’ll take a screenshot beforehand

This is very common with borrowed tech words.

You may also hear other expressions in real life, but スクリーンショットする is completely natural.

Literally, it means the map’s screen or the screen showing the map.

Breakdown:

• 地図 = map
• の = linking particle, often like of
• 画面 = screen / display

So 地図の画面 is the screen where the map is displayed, such as a map app screen on a phone.

In natural English, this would often be translated as:

• the map screen
• the map display
• the screen with the map on it

Because 地図の画面 is the direct object of スクリーンショットする.

The sentence is saying the speaker will screenshot the map screen.

So:

• 地図の画面を = the map screen
• スクリーンショットしておきます = I’ll take a screenshot of it beforehand

The を marks what is being screenshotted.

The non-past polite form here usually expresses the speaker’s present intention or future action:

• おきます = I will do it / I do it

So the sentence means something like:

• I’ll take a screenshot beforehand
• I’m going to take a screenshot beforehand

It sounds like the speaker is stating a plan politely.

If it were past tense:

• スクリーンショットしておきました
  = I took a screenshot beforehand / I had already taken a screenshot

In this sentence, ように is the more natural choice.

Why?

Because ように is commonly used when the purpose is expressed with:

• a negative form
• something to be achieved or avoided
• something not framed as a straightforward intentional action

Here the goal is:

• 迷わない = not get lost

So 迷わないように sounds very natural.

By contrast, ために often connects to clearer intentional purposes, especially with nouns or dictionary-form verbs:

• 日本語を勉強するために日本へ行きました。
  I went to Japan in order to study Japanese.

A learner should strongly remember:

• 忘れないように
• 遅れないように
• 迷わないように

These are very common patterns.

Yes, the subject is omitted, which is very normal in Japanese.

From おきます, we understand that the speaker is talking about their own action, so the implied subject is usually:

• I
• or sometimes we, depending on context

So the sentence naturally means:

• I’ll take a screenshot of the map screen beforehand so I won’t get lost.

Japanese often leaves out subjects when they are clear from context.
