会議の前に is the most straightforward pattern for before a noun:

• N の 前に = before N

So:

• 会議 = meeting
• 会議の前に = before the meeting

You may also sometimes see 会議前に, especially in shorter, more compact writing, but 会議の前に is very common and easy to understand.

They have different jobs:

• の connects 会議 and 前
  • literally something like the meeting’s before
  • in natural English: before the meeting
• に marks the time point when the action happens
  • 前に = before

So the whole phrase means before the meeting.

A useful pattern to remember is:

• N の 前に ... = before N ...
• N の 後で ... = after N ...

を marks the direct object of the verb.

Here, the verb is 共有した = shared, so ファイルを tells you what was shared.

• ファイルを共有した = shared the file / shared files

Even though English requires you to be more specific about number, Japanese often does not. So ファイル can mean:

• a file
• files
• the file
• the files

The exact meaning depends on context.

ごと is a suffix that can mean as a whole, along with, or including everything in it.

So フォルダごと means something like:

• together with the folder
• folder and all
• as an entire folder

In this sentence, it means the file(s) were shared with the folder as a whole, not one item at a time.

A similar idea in English would be:

• I shared it folder and all.

They are quite different:

• フォルダごと = together with each folder / as a whole folder / folder and all
• フォルダごとに = for each folder or by folder

So:

• フォルダごと共有した = shared it as an entire folder
• フォルダごとに共有した = shared it separately for each folder

The に changes the meaning a lot here.

Because Japanese usually puts modifiers before the verb.

The main action is:

• 共有した = shared

Everything before it gives more information about that action:

• 会議の前に = when it happened
• ファイルを = what was shared
• フォルダごと = how / in what form it was shared

So the sentence structure is very natural for Japanese: [time] [object] [manner/detail] [verb]

Japanese word order is more flexible than English, but the verb normally comes at the end.

Because Japanese often leaves out the subject when it is understood from context.

So this sentence does not explicitly say:

• who shared it
• whose file it was
• who it was shared with

That is normal in Japanese.

Depending on context, it could mean things like:

• I shared the file along with the whole folder before the meeting.
• We shared the files as a folder before the meeting.
• They shared it before the meeting.

Japanese often focuses on the action itself, and the listener figures out the subject from context.

共有した is the past form of 共有する.

• 共有する = to share
• 共有した = shared

It shows that the sharing was completed.

So the sentence describes a finished action: the sharing happened before the meeting, and the speaker is reporting it afterward.

If you changed it to 共有する, it would sound like a non-past statement such as a plan, habit, or future action depending on context.

Yes, but it is built from a noun plus する.

• 共有 = sharing / shared use
• 共有する = to share

This is a very common pattern in Japanese:

• 勉強する = to study
• 連絡する = to contact
• 共有する = to share

Then the past form is:

• 共有した = shared

So even though 共有 is originally a noun, 共有する works as a normal verb.

It could be either. Japanese nouns usually do not show singular/plural the way English does.

So ファイル can mean:

• a file
• files

You need context to know which is intended.

Because フォルダごと suggests a folder-level action, many learners may imagine multiple files, but grammatically ファイル itself does not force that reading.

No. In normal Japanese, this would usually be written without spaces:

会議の前に、ファイルをフォルダごと共有した。

Spaces are often added in teaching materials to help learners see the parts more clearly.

So the spaced version is learner-friendly, but the no-space version is what you would normally see in real Japanese.

Here are the common readings:

• 会議 → かいぎ
• 前 → まえ
• 共有した → きょうゆうした

So the sentence is read:

かいぎ の まえ に、ファイル を フォルダごと きょうゆうした。

フォルダ and ファイル are loanwords, so they are written in katakana.
