הקובץ המצורף לא נפתח אצלי, אז תוכלי לשלוח אותו שוב?

הקובץ means the file.

המצורף is an adjective/participle meaning attached. So together, הקובץ המצורף literally means the attached file.

Hebrew often uses a noun followed by an adjective, unlike English. So:

• קובץ מצורף = an attached file
• הקובץ המצורף = the attached file

The adjective comes after the noun and agrees with it in gender, number, and definiteness.

In Hebrew, when a noun is definite (the...), its adjective usually becomes definite too.

So:

• קובץ מצורף = an attached file
• הקובץ המצורף = the attached file

Both words get the sense of the. This is a very common Hebrew pattern:

• הילד הקטן = the small boy
• הספר החדש = the new book

So המצורף has ה־ because it describes הקובץ, which is already definite.

מצורף comes from the verb לצרף, which means to attach, to add, or to append.

In this sentence, מצורף means attached in the sense of an email attachment.

So הקובץ המצורף is the natural Hebrew way to say the attached file.

לא נפתח means did not open or more literally didn’t get opened / wasn’t opening.

This is different from לא פתחתי, which means I didn’t open.

The difference is important:

• לא פתחתי את הקובץ = I didn’t open the file
• הקובץ לא נפתח = the file didn’t open

In English, we often say the file wouldn’t open. Hebrew commonly uses נפתח for that idea.

נפתח is from the root פ־ת־ח (to open) in the נפעל pattern.

In this kind of sentence, נפתח is commonly used to mean something like:

• opened
• was opened
• would open
• managed to open

depending on context.

Here, הקובץ המצורף לא נפתח אצלי means something like:

• The attached file didn’t open for me
• I couldn’t open the attached file
• The attached file wouldn’t open on my end

It is a very natural Hebrew way to say that a file or program failed to open.

Because קובץ is a masculine singular noun.

Hebrew verbs and adjectives often agree with the noun they refer to. Since קובץ is masculine singular, the form is:

• נפתח = masculine singular

If the noun were feminine, you would use a feminine form. For example:

• התמונה לא נפתחה = the picture didn’t open

אצלי literally means at אצל + me, but in many contexts it means:

• for me
• on my end
• on my side
• in my case

So לא נפתח אצלי is a very natural way to say:

• it didn’t open for me
• it didn’t open on my end

This is more idiomatic than translating אצלי as physical location.

Related forms:

• אצלי = with me / at my place / on my end
• אצלך = with you / at your place / on your end
• אצלו = with him / on his end
• אצלה = with her / on her end

אז here means so.

The sentence structure is:

הקובץ המצורף לא נפתח אצלי, אז תוכלי לשלוח אותו שוב?
= The attached file didn’t open for me, so could you send it again?

Depending on context, אז can also mean then, but here it clearly connects the two parts of the sentence as so.

תוכלי is the future tense, second person feminine singular form of יכול (can / be able to).

Here it is used to make a polite request:

• תוכלי לשלוח אותו שוב? = Could you send it again?

This is addressed to one female.

Other versions would be:

• תוכל = to one male
• תוכלו = to more than one person, or sometimes polite plural

So this sentence is specifically speaking to a woman.

In Hebrew, future tense is very commonly used for requests, just as English uses forms like can you or could you.

So:

• תשלחי לי? can mean Will you send me...?
• תוכלי לשלוח...? means Could you send...?

This does not necessarily refer to the distant future. It is just the normal way to ask someone to do something.

Because Hebrew verbs already contain the subject information.

תוכלי already means you (feminine singular) will be able / can.

So you do not need to say את unless you want emphasis or contrast.

• תוכלי לשלוח אותו שוב? = normal, natural
• את תוכלי לשלוח אותו שוב? = more emphatic, like would you be able to send it again?

Hebrew often leaves out subject pronouns when the verb already makes the subject clear.

Because after יכול (can / be able to), Hebrew usually uses an infinitive.

So:

• תוכלי לשלוח = you can / could send
• literally: you will be able to send

This is a very common pattern:

• אני יכול לבוא = I can come
• היא יכולה לעזור = she can help
• תוכלי לכתוב לי? = could you write to me?

אותו means it / him, and here it refers to הקובץ (the file).

So:

• לשלוח אותו שוב = to send it again

Hebrew often includes the object pronoun when English would too. Without אותו, the sentence would still be understandable in some contexts, but אותו makes it clear that the speaker means the file.

Because אותו here is already a direct object pronoun by itself.

Compare:

• לשלוח את הקובץ = to send the file
• לשלוח אותו = to send it

When Hebrew uses a full definite noun like הקובץ, it often needs את as the direct object marker.

But with object pronouns like אותו, אותה, אותם, you do not add a separate את before them.

שוב means again.

So:

• לשלוח אותו שוב = send it again

Yes, עוד פעם also means again / one more time, and in many situations it would work too:

• תוכלי לשלוח אותו עוד פעם?

That sounds natural as well.
שוב is a bit more concise and slightly more neutral in tone, while עוד פעם can feel a bit more conversational.

Yes. It sounds natural and reasonably polite.

תוכלי לשלוח אותו שוב? is a normal way to ask Could you send it again?

It is not extremely formal, but it is polite and appropriate in many everyday situations, including email or messaging, especially if you know the person.

If you wanted to sound a bit more formal, you could say something like:

• הקובץ המצורף לא נפתח אצלי. תוכלי בבקשה לשלוח אותו שוב?
• הקובץ המצורף לא נפתח אצלי. האם תוכלי לשלוח אותו שוב?

Adding בבקשה can make it sound a little softer.

Yes. The form תוכלי shows that the speaker is talking to one female.

If speaking to a man, you would say:

• הקובץ המצורף לא נפתח אצלי, אז תוכל לשלוח אותו שוב?

If speaking to several people, you would say:

• הקובץ המצורף לא נפתח אצלי, אז תוכלו לשלוח אותו שוב?

So Hebrew makes this distinction directly in the verb.

A simple transliteration would be:

ha-kovetz ha-metzuraf lo niftach etzli, az tukhli lishloach oto shuv?

A rough pronunciation guide:

• הקובץ = ha-KO-vets
• המצורף = ha-me-tsu-RAF
• לא נפתח = lo nif-TAKH
• אצלי = ets-LEE
• אז = az
• תוכלי = tukh-LEE
• לשלוח = lish-LO-ach
• אותו = o-TO
• שוב = shoov

Yes. In real usage, לא נפתח אצלי can be a little flexible.

Depending on context, it may suggest:

• it didn’t open for me
• it isn’t opening for me
• it won’t open on my end

That kind of flexibility is common in everyday Hebrew, especially in tech-related situations. The main idea is that the file could not be opened successfully.
