Elimino i file che non servono.

In Italian, the subject pronoun is often omitted because the verb ending already shows who is doing the action.

• elimino = I delete / I remove
• the -o ending tells you the subject is io

So Elimino i file che non servono is completely natural.
You could say Io elimino i file che non servono if you want extra emphasis on I, for example to contrast with someone else.

Elimino is the present indicative of eliminare.

In English, the Italian present tense can correspond to different English forms depending on context:

• I delete
• I am deleting
• sometimes even I do delete

So Elimino i file che non servono could mean either a habitual action or something happening now, depending on the situation.

I is the plural definite article used with most masculine plural nouns.

Here:

• il file = the file
• i file = the files

So the sentence is talking about the files.

Because file is a borrowed word, and in standard Italian many borrowed nouns are invariable.

That means:

• il file = the file
• i file = the files

The article changes, but the noun stays the same.

A learner may expect something like files, but standard Italian normally does not add the English plural -s.

In this sentence it is treated as masculine, which is why you get:

• il file
• i file

That is the normal gender for file in modern Italian.

In Italian, articles are used more often than in English.
Here, i file sounds natural because you are referring to a specific set or category of files: the files that are not needed.

Without the article, the sentence would sound unnatural in standard Italian.

Here che is a relative pronoun. It introduces the clause that describes i file.

So:

• i file = the files
• che non servono = that are not needed / that aren’t needed

In English, che often corresponds to that, which, or sometimes who, depending on the noun it refers to.

Because the subject of servire in that clause is i file, which is plural.

Break it down like this:

• i file = plural
• servono = are needed / are useful for a plural subject

Compare:

• Il file non serve. = The file is not needed.
• I file non servono. = The files are not needed.

So the verb agrees with file.

Here servire does not mean to serve in the restaurant/waiter sense.
It means something like:

• to be useful
• to be needed
• to be of use

So i file che non servono means the files that are no longer useful / needed.

This is a very common Italian use of servire.

Both are possible, but non servono is very natural and idiomatic in everyday Italian.

Compare:

• i file che non servono = the files that aren’t needed
• i file che non sono necessari = the files that are not necessary

The second version sounds a bit more formal or explicit.
The original sentence is more direct and conversational.

Because this is a restrictive relative clause: it identifies which files are being deleted.

The meaning is:

• not all files
• only the files that are not needed

Since the clause is essential to the meaning, Italian normally does not put a comma there.

If you added a comma, it could suggest that all the files are unnecessary, which changes the meaning.

Yes. Cancello is also very common and often means I delete in computer contexts.

There can be a slight nuance:

• eliminare often sounds like remove/eliminate
• cancellare often sounds like delete/erase

But in many everyday contexts, especially with digital files, both can work.

In Italian, file is usually pronounced approximately FEE-leh.

So it is not pronounced exactly like English file.

That gives you:

• il file
• i file

with an Italian-style pronunciation.

It can do both. The Italian present tense is flexible.

Depending on context, it can mean:

• a habit: I delete files I don’t need
• something happening now: I’m deleting the files that aren’t needed

Italian often relies on context where English might choose between I delete and I am deleting.

No, in this kind of Italian sentence che must be expressed.

English can say:

• the files that I need
• the files I need

But Italian normally requires the relative pronoun:

• i file che servono
• i file che non servono

So you cannot normally omit che here.
