Wenn du den Dateinamen kennst, gib ihn einfach in die Suchleiste ein; dann springt der Cursor an die richtige Stelle.

Because wenn introduces a subordinate clause, and in German subordinate clauses the conjugated verb typically goes to the end.

So:

• Wenn du den Dateinamen kennst = If you know the file name

Compare:

• Main clause: Du kennst den Dateinamen.
• Subordinate clause: ..., wenn du den Dateinamen kennst.

This is one of the most important word-order patterns in German.

Wenn is used here for if.

• wenn = if / whenever
• als = when for a single event in the past
• ob = whether

So:

• Wenn du den Dateinamen kennst ... = If you know the file name ...

But:

• Als ich jung war ... = When I was young ...
• Ich weiß nicht, ob er kommt. = I don’t know whether he is coming.

Because Dateiname is masculine: der Dateiname.

In this sentence, it is the direct object of kennen, so it must be in the accusative case:

• Nominative: der Dateiname
• Accusative: den Dateinamen

So:

• du kennst den Dateinamen

Also notice that masculine nouns often change the article in the accusative from der to den.

Because Dateiname is one of the masculine nouns whose accusative singular is den Dateinamen.

This is just the normal form for this noun:

• Nominative: der Dateiname
• Accusative: den Dateinamen

The -n belongs to the declined form of the noun in this case.

German often uses kennen with nouns and wissen with facts, information, or clauses.

Here the object is a noun phrase:

• den Dateinamen

So kennen is natural:

• den Dateinamen kennen

Compare:

• Ich kenne den Namen. = I know the name.
• Ich weiß, wie der Name lautet. = I know what the name is.

A learner may expect wissen because English uses know for both ideas, but German usually separates them.

Because this is the du-imperative of geben.

The informal singular command of geben is:

• gib! = give! / enter!

In German, geben is a strong verb, so the stem vowel changes from e to i in this form.

Compare:

• du gibst
• Imperative: gib!

So:

• gib ihn einfach ... ein = just enter it ...

Because the verb is eingeben, which is a separable verb.

In a main clause, the prefix splits off and goes to the end:

• eingeben → gib ... ein

So:

• Gib ihn in die Suchleiste ein.

Compare:

• Infinitive: den Namen eingeben
• Main clause: Ich gebe den Namen ein.
• Imperative: Gib den Namen ein.

This is very common in German with verbs like:

• anfangen
• aufmachen
• mitkommen
• eintragen

Because ihn refers back to den Dateinamen.

Since Dateiname is masculine, the accusative pronoun is:

• er → nominative
• ihn → accusative

So:

• den Dateinamen → ihn

This is exactly like replacing the file name with it in English, except German pronouns must match grammatical gender.

German word order often puts pronouns earlier in the sentence than adverbs like einfach.

So this sounds natural:

• gib ihn einfach ... ein

A version like gib einfach ihn ... ein is much less natural here.

A useful rule of thumb is:

• short pronouns often come early
• adverbs such as einfach, heute, wahrscheinlich often come after them

Because in here expresses direction: you are entering something into the search bar.

With two-way prepositions like in, German uses:

• accusative for direction/movement
• dative for location

So:

• in die Suchleiste = into the search bar
• in der Suchleiste = in the search bar

Since the idea is placing text into the bar, the accusative is used.

The semicolon links two closely related main clauses.

Here the first part gives the instruction, and the second part gives the result:

• Wenn du den Dateinamen kennst, gib ihn einfach in die Suchleiste ein;
• dann springt der Cursor an die richtige Stelle.

A full stop would also be possible in many contexts, but the semicolon shows a particularly close connection between the two thoughts.

Because German main clauses follow the verb-second rule.

If dann comes first, the conjugated verb must come next:

• Dann springt der Cursor ...

So the structure is:

1. dann
2. springt
3. der Cursor

Compare:

• Der Cursor springt dann an die richtige Stelle.
• Dann springt der Cursor an die richtige Stelle.

Both are correct; the position of dann changes the word order.

Because Cursor is a masculine noun in German:

• der Cursor

So in the sentence:

• der Cursor springt ...

It is the subject, so it appears in the nominative case.

Because an is another two-way preposition, and here it expresses movement toward a position.

The cursor jumps to the correct place, so German uses the accusative:

• an die richtige Stelle

If you were describing location instead of movement, you would use the dative:

• Der Cursor ist an der richtigen Stelle. = The cursor is in the correct place.

So:

• movement/change of position → an die richtige Stelle
• fixed location → an der richtigen Stelle

Not literally. springen normally means to jump, but German often uses it figuratively for things that move suddenly from one position to another.

So:

• der Cursor springt an die richtige Stelle

means something like:

• the cursor jumps/moves straight to the correct position

This is idiomatic and very natural in technical or computer-related German.

Yes. du is the informal singular you.

So the sentence is addressing one person in a friendly, direct way, which is very common in instructions, software help texts, tutorials, and everyday communication.

If it were formal, you would expect something like:

• Wenn Sie den Dateinamen kennen, geben Sie ihn einfach in die Suchleiste ein ...

Possibly, depending on the interface, but the meaning is not always exactly the same.

• die Suchleiste = search bar
• das Suchfeld = search field / search box

Both can be correct in context, but Suchleiste suggests a bar-shaped search area, while Suchfeld is a more general term for the box where you type.
