Ben dosyayı göndermeden önce şifreliyorum.

Yes. Turkish often drops subject pronouns because the verb ending already shows who is doing the action.

So:

• Şifreliyorum already means I am encrypting / I encrypt
• Ben şifreliyorum adds emphasis or clarity: I am encrypting

In this sentence, ben is not required grammatically. It may be there to stress the subject, contrast with someone else, or simply because the speaker chose to include it.

Because dosyayı is the definite direct object form.

Breakdown:

• dosya = file
• dosya-y-ı = the file

The ending -(y)ı / -(y)i / -(y)u / -(y)ü is the accusative case, used when the direct object is specific or definite.

So:

• dosya şifreliyorum would sound like I am encrypting a file / files in a more indefinite sense, though this exact form may sound less natural depending on context.
• dosyayı şifreliyorum = I am encrypting the file / I encrypt the file

The y is a buffer letter inserted between vowels.

It means before sending or before I send.

This structure is made from:

• göndermek = to send
• verb stem: gönder-
• -meden / -madan = without doing / in expressions like before doing
• önce = before

So:

• göndermeden önce literally looks like before not-sending, but in actual Turkish usage this whole pattern means before sending

This is a very common construction:

• gitmeden önce = before going
• yemeden önce = before eating
• konuşmadan önce = before speaking

Because of vowel harmony.

The suffix has two main forms:

• -madan
• -meden

Which one you use depends on the last vowel in the verb stem.

In gönder-, the relevant vowel is e, so the correct form is:

• göndermeden

Compare:

• bakmadan önce = before looking
• gelmeden önce = before coming

It can mean either, depending on context.

In this sentence, because the main verb is şifreliyorum (I am encrypting), the natural understanding is:

• I encrypt the file before sending it
• or Before I send the file, I encrypt it

Turkish often leaves the subject of the subordinate action understood from context rather than stating it explicitly.

If you wanted to make the subject more explicit, Turkish has other ways to do that, but in everyday speech this form is very normal.

Şifreliyorum is the present continuous form, but in Turkish this tense is used more broadly than English am doing.

It can mean:

• I am encrypting
• I encrypt
• I do encrypt
• sometimes even a habitual action, depending on context

Breakdown:

• şifrele- = to encrypt
• -iyor = present continuous marker
• -um = I

So:

• şifreliyorum = I am encrypting / I encrypt

By contrast, şifrelerim is the aorist and often suggests a habitual action, general rule, or regular practice:

• Ben dosyayı göndermeden önce şifrelerim = I encrypt the file before sending it as a habit / general practice

Both can work, but they create slightly different nuances.

This happens because of how the -iyor suffix joins the verb stem.

The verb is:

• şifrele-

When the present continuous suffix is added, the final vowel of the stem combines smoothly with the suffix, giving:

• şifreliyor-

Then add the first-person ending:

• şifreliyorum

This is a normal pattern in Turkish:

• beklemek → bekliyorum
• dinlemek → dinliyorum
• şifrelemek → şifreliyorum

So the form may look irregular at first, but it follows a common sound pattern.

The sentence is:

• Ben dosyayı göndermeden önce şifreliyorum.

A useful way to see it is:

• Ben = subject
• dosyayı = object
• göndermeden önce = time clause (before sending)
• şifreliyorum = main verb

Turkish usually puts the main verb at the end, so this is a very natural order.

A rough structure is:

Subject + Object + Time expression + Verb

However, Turkish word order is flexible, and other orders are possible for emphasis:

• Dosyayı ben göndermeden önce şifreliyorum.
• Göndermeden önce dosyayı şifreliyorum.

The original version is straightforward and neutral.

It often means to encrypt, but in real usage it can sometimes be used more loosely for protecting with a password or coding/encoding something, depending on context.

So learners should know:

• In technical contexts, şifrelemek commonly means to encrypt
• In everyday speech, Turkish speakers may sometimes use it a bit more broadly

Related word:

• şifre can mean password, code, or cipher, depending on context

That broader meaning can be confusing for English speakers, since English separates password, code, and encryption more sharply in many contexts.

Yes. Turkish allows some flexibility.

For example:

• Dosyayı şifreliyorum göndermeden önce.
• Göndermeden önce dosyayı şifreliyorum.

These are understandable, but the most standard and neutral version is usually:

• Dosyayı göndermeden önce şifreliyorum.

Putting önce after the -meden form is the normal pattern:

• gitmeden önce
• uyumadan önce
• kontrol etmeden önce

So the important chunk to learn is:

verb + -madan/-meden + önce

Yes. That is one of the tricky things for English speakers.

Even though şifreliyorum is formally the present continuous, Turkish often uses this tense for actions that are regular, characteristic, or part of a routine.

So the sentence can mean:

• I am encrypting the file before sending it
  or
• I encrypt the file before sending it

The exact meaning depends on context.

If the speaker is describing their normal practice, this sentence can still sound natural. If they want to sound more clearly habitual or rule-like, they might also use the aorist:

• Ben dosyayı göndermeden önce şifrelerim.

Because Turkish often leaves repeated objects understood when the meaning is clear.

In English, we often say:

• I encrypt the file before sending it

In Turkish, the it does not need to be repeated here. The listener naturally understands that the thing being sent is the same file already mentioned.

So:

• Ben dosyayı göndermeden önce şifreliyorum.

naturally implies:

• I encrypt the file before sending it

If needed, Turkish can be more explicit in other ways, but it usually prefers not to repeat information unnecessarily.

Yes. One common alternative uses a verbal noun plus a possessive ending:

• Dosyayı göndermeden önce şifreliyorum.
• Dosyayı göndermeden önce onu şifreliyorum. (more explicit, but often unnecessary)
• Dosyayı göndermeden önce şifrelerim. (more habitual)
• Dosyayı göndermeden önce dosyayı şifrelerim. (grammatically possible, but repetitive)

There are also more formal or more explicitly subordinated structures in Turkish, but for everyday use, -meden önce is one of the most common and useful patterns to learn for before doing something.
