Dosya eki çok büyük olunca e-posta gitmedi; hesap makinesi dosyasını ayrıca yükledim.

Olunca comes from olmak and the ending -ınca / -ince, which often means when, once, since, or because depending on context.

Here, çok büyük olunca means something like when it was too big or more naturally because it was too big.

So this ending does not always mean only time. It can also introduce the reason for what happens next.

Both can relate to a situation, but they are not exactly the same.

• çok büyükken = while it was very big / when it was very big
• çok büyük olunca = when it became/was very big, often with a stronger sense of result or cause

With adjectives, Turkish often uses olmak to express the idea of becoming or ending up in a state. In this sentence, olunca works very naturally because it connects that state to the next event: the email did not go.

So çok büyük olunca sounds like:

• because it was too big
• since it turned out to be too big

Dosya eki is a noun compound.

It is made of:

• dosya = file
• ek-i = attachment / added item, with the compound ending

In Turkish, a very common noun-compound pattern is:

noun + noun-with-3rd-person-possessive-ending

So:

• dosya eki = file attachment

This is an indefinite noun compound. English often uses two nouns side by side, and Turkish often does something similar, but the second noun usually takes this special ending.

Yes, literally it is the email didn’t go, and that is very natural Turkish.

Turkish often uses gitmek for messages, mail, emails, and similar things to mean:

• be sent
• go through
• reach the destination

So e-posta gitmedi can mean:

• the email didn’t send
• the email didn’t go through
• the email wasn’t delivered

This is one of those places where Turkish uses a simple everyday verb, while English often prefers a more technical passive expression.

Gitmedi can be broken down like this:

• git- = go
• -me- = negative
• -di = past tense

So:

• gitti = it went
• gitmedi = it didn’t go

There is no separate word for it here. Turkish often leaves the subject understood from context. In this sentence, the subject is e-posta.

Yes, literally it comes from words related to calculation and machine, and it means calculator.

It is a fixed expression:

• hesap = calculation/account
• makinesi = machine

So hesap makinesi is simply the normal Turkish word for calculator.

Like dosya eki, this is also a noun compound.

Because it contains both a compound ending and the accusative ending.

Break it down like this:

• dosya = file
• dosya-sı = its file / the file, as the head of a noun compound
• dosya-sı-nı = the file, as a specific direct object

In hesap makinesi dosyasını:

• hesap makinesi dosyası = calculator file
• hesap makinesi dosyasını = the calculator file, as the thing being uploaded

The -nı is the accusative marker, and it appears because this is a definite/specific direct object.

That n is a buffer consonant.

The word already has the 3rd-person possessive ending:

• dosyası

When Turkish adds another vowel-starting suffix after that, it often inserts n to make pronunciation smoother:

• dosyası + ı becomes dosyasını

So the n is not a separate meaning by itself here. It is just a linking sound used after that possessive ending.

Ayrıca means also, additionally, or separately, depending on context.

In this sentence, separately is the best fit:

• ayrıca yükledim = I uploaded it separately

It tells you that this was done as an extra step, apart from the email that failed.

Yükledim breaks down like this:

• yükle- = upload / load
• -di- = past tense
• -m = I

So:

• yükledim = I uploaded / I loaded

Turkish usually does not need the pronoun ben because the ending -m already shows that the subject is I.

Because Turkish very often drops subject pronouns when the verb ending already makes the subject clear.

In yükledim, the ending -m already means I.

So:

• Ben yükledim = I uploaded it
• Yükledim = I uploaded it

Both are grammatical, but leaving out ben is usually more natural unless you want emphasis.

Yes. Turkish word order is flexible, although some versions sound more neutral than others.

The given sentence is natural because it presents:

1. the reason first
2. then the result
3. then the follow-up action

For example, the second clause could be rearranged:

• Hesap makinesi dosyasını ayrıca yükledim
• Ayrıca hesap makinesi dosyasını yükledim

Both are possible, but the original version sounds balanced and clear.

Also, Turkish often places the most important new information close to the verb or just before it, so word order can shift for emphasis.

The semicolon links two closely related statements without using a separate connecting word.

Here it shows:

• first, the email did not go through because the attachment was too big
• second, as a consequence, the speaker uploaded the calculator file separately

Using a semicolon makes the relationship feel tight and logical. It is similar to writing two connected clauses in English with a semicolon.

You could also express the connection with words such as bu yüzden or o yüzden, but the semicolon keeps it short and clean.
