Comprobamos el archivo digital durante el control de calidad.

Comprobamos comes from comprobar, which means to check, to verify, or to make sure.

In this sentence, it means that we check / verify the digital file.

Compared with similar verbs:

• comprobar = check/verify that something is correct
• revisar = review/look over
• verificar = verify, often a bit more formal or technical

So comprobamos suggests checking that the file is correct or in order.

It can be either one, depending on context.

For -ar verbs, the nosotros form is the same in:

• present: comprobamos = we check
• preterite: comprobamos = we checked

So this form is ambiguous on its own. Native speakers usually understand it from context.

For example:

• Cada día comprobamos el archivo digital. = Every day we check the digital file.
• Ayer comprobamos el archivo digital. = Yesterday we checked the digital file.

Because Spanish often drops subject pronouns when they are not needed.

The ending -amos already tells you the subject is we. So comprobamos already includes the idea of we.

You could say:

• Nosotros comprobamos el archivo digital durante el control de calidad.

But it usually sounds more natural to leave nosotros out unless you want emphasis or contrast, for example:

• Nosotros comprobamos el archivo digital, pero ellos no.

Spanish uses articles much more often than English.

Here, el archivo digital means the digital file, referring to a specific file or to the file relevant in that situation.

In English, you might sometimes say We checked digital file data only in very special styles, but in normal Spanish you usually need the article:

• Comprobamos el archivo digital.

Without the article, archivo digital would usually not sound complete in a normal sentence.

Yes, archivo can mean file, record, or archive, depending on context.

In this sentence, archivo digital most naturally means digital file.

A useful note for Spain: in computing, fichero is also common for file. So depending on context, a Spanish speaker from Spain might also say:

• Comprobamos el fichero digital...

But archivo digital is still understandable and correct.

Because in Spanish, most adjectives normally come after the noun.

So:

• archivo digital = digital file
• control de calidad = quality control

Putting digital before the noun would sound unusual here and could create a more literary or emphatic effect, not the normal neutral wording.

This noun + adjective order is very common in Spanish:

• documento oficial
• sistema automático
• archivo digital

Durante means during and is used before a noun phrase.

So:

• durante el control de calidad = during quality control

This is the right choice because el control de calidad is a noun phrase, not a full clause.

Compare:

• durante el control de calidad = during quality control
• mientras comprobábamos el sistema = while we were checking the system

Use durante with a noun, but mientras with a verb clause.

Literally, control de calidad means control of quality.

Spanish often uses noun + de + noun where English uses a compound noun:

• control de calidad = quality control
• centro de datos = data centre
• sala de espera = waiting room

So de links the two nouns together. This is one of the most common patterns in Spanish.

Yes. Spanish word order is more flexible than English, especially with time expressions.

You can say:

• Comprobamos el archivo digital durante el control de calidad.
• Durante el control de calidad, comprobamos el archivo digital.

Both are correct.

The second version puts more focus on when the action happened. The first is the more neutral order.

A simple approximation is:

kom-pro-BA-mos el ar-CHEE-vo dee-hee-TAL du-RAN-te el kon-TROL de ka-lee-DAD

A few useful pronunciation notes:

• comprobamos: stress on ba
• archivo: ch sounds like English ch
• digital: the g before i sounds like the Spanish j, a throaty sound
• control: stress on the last syllable
• calidad: stress on the last syllable

If you want a more Spain-specific note, the pronunciation of g in digital is the same general sound used in standard Peninsular Spanish.

If you mean more than one file, you would change both the noun and the adjective:

• Comprobamos los archivos digitales durante el control de calidad.

Changes:

• el → los
• archivo → archivos
• digital → digitales

This is because adjectives in Spanish must agree with the noun in number (and also in gender, when relevant).

Yes, but the meaning changes slightly.

• comprobamos = we check/verify that it is correct
• revisamos = we review/look over it
• verificamos = we verify it, often more formally

So:

• Comprobamos el archivo digital suggests checking whether it is correct.
• Revisamos el archivo digital suggests examining or reviewing it.
• Verificamos el archivo digital sounds a bit more technical or formal.

All can work, but comprobamos is a good choice if the idea is checking accuracy or correctness.
