Le nom de fichier est disponible dans les métadonnées.

Because nom is a masculine noun in French, so it takes the masculine singular article le.

• le nom = the name
• un nom = a name

This is something you simply have to memorize with the noun.

This is a very common question. The difference is important:

• le nom de fichier = the file name / file name as a type or category
• le nom du fichier = the name of the file (a specific file)

So in your sentence, nom de fichier works like a compound noun: file name.

Compare:

• Le nom de fichier est trop long. = The file name is too long.
• Le nom du fichier est trop long. = The name of the file is too long.

English often uses noun + noun (file name), but French usually uses noun + de + noun.

Because de + noun is often used in French to express a category, function, or type.

Here, fichier is not being presented as a specific file. It is describing what kind of name it is: a file name.

This happens in many common expressions:

• une tasse de thé = a cup of tea
• une salle de bain = a bathroom
• un nom de fichier = a file name

But if you mean a specific file, you would use an article:

• le nom du fichier = the name of the file

The subject is Le nom de fichier.

The sentence breaks down like this:

• Le nom de fichier = subject
• est = verb (is)
• disponible = adjective
• dans les métadonnées = prepositional phrase (in the metadata)

So the basic structure is:

[Subject] + [verb] + [adjective] + [location]

No. Disponible is an adjective, not a verb.

• est = is
• disponible = available

So est disponible literally means is available.

This is a very common French pattern:

• Le document est prêt. = The document is ready.
• L’information est utile. = The information is useful.
• Le nom de fichier est disponible. = The file name is available.

Its main meaning is available, but in technical contexts it can also feel close to:

• accessible
• present
• provided
• found

In this sentence, it suggests that the file name can be accessed or found in the metadata.

So depending on context, an English speaker might understand it as:

• is available in the metadata
• can be found in the metadata
• is present in the metadata

Because métadonnées is usually used in the plural in French, just as metadata often refers to a set of data about data.

• une métadonnée = a piece of metadata / one metadata item
• les métadonnées = the metadata

In real usage, the plural is much more common when talking about metadata as a whole.

Because French usually requires an article before a noun. Here, les métadonnées means the metadata.

French uses articles more consistently than English does. Even when English sometimes drops the article, French often keeps one.

So:

• dans les métadonnées = in the metadata

This is perfectly normal French structure.

A careful approximate pronunciation is:

Le nom de fichier est disponible dans les métadonnées
luh non duh fee-shyay eh dee-spo-neebl dahn lay may-ta-do-nay

A few notes:

• nom sounds roughly like non but with a nasal vowel
• fichier sounds like fee-shyay
• est is pronounced eh
• dans has a nasal vowel
• métadonnées ends like do-nay

There is also a liaison possibility in careful speech between est and disponible, so you may hear:

• est disponible ≈ eh dis-po-neebl
• sometimes with a light t link in very formal/careful speech: eh-t dis-po-neebl

Actually, the word order here is very similar to English:

• Le nom de fichier = The file name
• est disponible = is available
• dans les métadonnées = in the metadata

French often follows the same basic order as English in simple statements:

subject + verb + complement

The main difference is inside nom de fichier, where French uses noun + de + noun instead of the English noun + noun pattern.

No, that would not be natural French.

English allows noun-noun combinations very easily, like file name, user account, data table. French usually does not build compounds that way. Instead, it often uses de:

• nom de fichier = file name
• compte d’utilisateur = user account
• table de données = data table

So Le nom de fichier... is the correct structure.

Fichier is masculine.

• un fichier = a file
• le fichier = the file

That matters in other sentences, for example:

• Le fichier est prêt.
• Un fichier a été ajouté.

But in nom de fichier, the article agrees with nom, not with fichier, because nom is the main noun.

Yes, depending on context.

French technical writing often uses être disponible in places where English might prefer:

• is available
• is provided
• can be found
• is present

So if the context is software, documentation, or data fields, can be found in the metadata may sound more natural in English, even though the French wording is est disponible dans les métadonnées.

Yes, it sounds neutral and somewhat technical, especially because of words like:

• fichier = file
• métadonnées = metadata
• disponible = available

It is the kind of sentence you might see in:

• software documentation
• interface instructions
• API docs
• technical manuals

It is grammatically simple, but the vocabulary is technical.
