Après l’archivage, je mets le doublon dans la corbeille.

It literally means After the archiving.

In natural English, you would usually translate it as After archiving or Once the file has been archived.

French often uses a noun here:

• l’archivage = the archiving / the filing / the process of archiving

So the structure is:

• après = after
• l’archivage = the archiving

Together: Après l’archivage = After archiving

French normally uses an article before nouns much more often than English does.

So:

• archivage = archiving, as a dictionary form
• l’archivage = the archiving

The le becomes l’ because archivage starts with a vowel sound. This is called elision.

Compare:

• le document
• l’archivage

So l’archivage is just le archivage shortened to sound natural.

French often expresses this idea with a noun, especially in administrative, technical, or formal language.

So:

• Après l’archivage sounds quite natural in office, IT, or procedural contexts.

A more verbal alternative is:

• Après avoir archivé = After having archived / After archiving

Both are correct, but they feel slightly different:

• Après l’archivage = more formal, procedural, or technical
• Après avoir archivé = more directly verbal and often more conversational

Because the verb is mettre and its je form in the present tense is je mets.

Present tense of mettre:

• je mets
• tu mets
• il / elle / on met
• nous mettons
• vous mettez
• ils / elles mettent

So je mets is simply the correct conjugation.

A useful detail: although mets ends in -s, that -s is not pronounced here.

It is pronounced roughly like zhuh meh.

More precisely:

• je sounds like zhuh
• mets sounds like meh

Important point:

• mets
• met

are pronounced the same in normal speech.

So:

• je mets
• il met

sound different only because of je vs il, not because of mets vs met.

Le doublon means the duplicate.

In this kind of sentence, it usually refers to:

• a duplicate file
• a duplicate document
• a duplicate record
• an extra copy that should not be kept

It is a bit more specific than la copie:

• une copie = a copy
• un doublon = a duplicate, often an unwanted extra version

So in a computer or office context, le doublon strongly suggests the duplicate item that should be deleted.

Le suggests that the duplicate is already known or identifiable from the context.

So:

• un doublon = a duplicate, one duplicate, any duplicate
• le doublon = the duplicate, the specific duplicate we are talking about

This is very common in instructions or procedures, where the item has already been identified.

For example:

• Repérez le doublon, puis mettez-le dans la corbeille. = Identify the duplicate, then put it in the trash.

It means in the trash, in the bin, or in a computer context, in the recycle bin / trash folder.

Corbeille can mean:

• a physical wastebasket
• a computer trash / recycle bin

In this sentence, because of words like archivage and doublon, it very likely refers to the computer trash.

So:

• mettre le doublon dans la corbeille = put the duplicate in the trash / recycle bin

Because the verb mettre usually takes dans when you are putting something inside something.

So:

• mettre dans = put into / put inside

Examples:

• mettre un livre dans un sac = put a book in a bag
• mettre un fichier dans un dossier = put a file in a folder
• mettre le doublon dans la corbeille = put the duplicate in the trash

Using à here would not sound natural for the idea of placing something inside the bin.

The comma separates the introductory time phrase from the main clause.

So the sentence is structured like this:

• Après l’archivage = introductory phrase telling you when
• je mets le doublon dans la corbeille = main clause

This is similar to English:

• After archiving, I put the duplicate in the trash.

The comma helps readability. In French, this kind of comma is very common, especially when the opening phrase is a bit long or formal.

Because it uses the present tense (je mets), it most naturally sounds like:

• a habitual action
• a step in a procedure
• a description of what someone does regularly

So it can mean something like:

• After archiving, I put the duplicate in the trash
• Once the file is archived, I put the duplicate in the trash

If you wanted to describe one completed past action, French would normally use a past tense, for example:

• Après l’archivage, j’ai mis le doublon dans la corbeille.

Yes. Here are a few natural alternatives, with slightly different tones:

• Après avoir archivé, je mets le doublon dans la corbeille. More verbal; still natural.

• Une fois l’archivage effectué, je mets le doublon dans la corbeille. More formal and procedural.

• Après l’archivage, je supprime le doublon. This means After archiving, I delete the duplicate, which may be more direct in a digital context.

The original sentence is perfectly natural, especially in administrative or technical language.
