Il dispositivo non apre il file.

Il is the masculine singular definite article in Italian, equivalent to the in English.

So:

• il dispositivo = the device

Italian uses articles very regularly, often more regularly than English. Since dispositivo is a singular masculine noun, il is the correct article here.

In Italian, the usual way to make a sentence negative is to put non directly before the verb.

So:

• apre = opens
• non apre = does not open

This is the normal pattern in simple sentences:

• Non funziona = it does not work
• Non legge il file = it does not read the file

Aprire is the infinitive form, meaning to open.
In a full sentence, Italian normally uses a conjugated verb, not the infinitive.

Here, the subject is il dispositivo, which is third person singular, so the verb must match it:

• aprire = to open
• apre = it opens

So Il dispositivo non apre il file uses the correct present-tense form for it/the device.

Apre is the present indicative form of aprire.

It can often correspond to English:

• opens
• is opening
• sometimes even does open, depending on context

In this sentence, it simply states what the device does or does not do in the present: it does not open the file.

Because file is also being treated as a masculine singular noun here, so it takes the definite article il:

• il file

So the structure is:

• Il dispositivo = the subject
• non apre = the verb
• il file = the direct object

Italian usually keeps the article with the noun unless there is a reason not to.

Yes. File is a loanword from English, but it is widely used in Italian.

A few useful things to know:

• It is usually treated as masculine singular: il file
• Its plural is usually unchanged in form: i file

So:

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

This is common with many modern borrowed words in Italian.

This is the standard Italian word order: subject + verb + object.

So:

• Il dispositivo = subject
• non apre = verb
• il file = object

That makes the sentence straightforward and neutral. Italian can sometimes change word order for emphasis, but this version is the most normal one.

Yes, in many contexts you could.

Italian often omits subject pronouns because the verb ending already gives information about the person and number. With a noun subject like il dispositivo, you can still leave it out if the context already makes clear what you are talking about.

So:

• Il dispositivo non apre il file = fully explicit
• Non apre il file = possible if it is already obvious that the subject is the device

Including il dispositivo makes the sentence clearer and more specific.

Usually, yes, but the exact English equivalent can depend on context.

Dispositivo is a fairly general word and can refer to:

• a device
• an apparatus
• a piece of equipment
• sometimes a hardware unit

In tech contexts, it often means device, especially for electronic equipment.

Yes, depending on the situation.

Aprire un file is very common and natural. But Italian can also use other expressions, such as:

• leggere un file = to read a file
• caricare un file = to load a file
• accedere a un file = to access a file
• riuscire ad aprire un file = to manage to open a file

For example:

• Il dispositivo non riesce ad aprire il file means the device is unable to open the file, which sounds a bit more explicit than simply non apre.

Apre is pronounced roughly AH-preh.

A few pronunciation notes:

• a is a clear open vowel, like a in father
• pr is pronounced together
• final e is pronounced, not silent

So it is not like English ape or apray. It is two clear syllables: a-pre.
