Questions & Answers about Fue el archivo lo que lograron manipular.
Why does the sentence use lo que instead of just que?
In this type of cleft sentence, lo que acts as a neuter pronoun meaning 'the thing that' or 'what'. Even though el archivo is a masculine noun, using lo que frames the whole action as an abstract concept: 'the thing they managed to manipulate'. You could also just use que, but lo que makes the emphasis on the file slightly stronger.
Does the tense of the verb ser always have to match the main action?
Usually, yes. Because the tampering happened in the past (lograron), the verb ser also takes the preterite past tense (fue). While you will sometimes hear native speakers use the present tense for the first part (Es el archivo lo que lograron manipular), matching the tenses is the standard rule for cleft sentences.
I know lograr means 'to achieve', but how does it work with another verb here?
When lograr is followed directly by an infinitive like manipular, it translates to 'to manage to do' something. Notice that unlike English, which requires the preposition 'to' (managed to tamper), Spanish connects lograr directly to the infinitive without any extra connecting words.
Could I flip the word order and start the sentence with lo que?
