Always close files! Leaving files open can cause data loss or corruption.
This study notes covers Deep Dive: Reading All Lines within File Handling for GCSE Computer Science. Revise File Handling in 3.2 Programming for GCSE Computer Science with 15 exam-style questions and 10 flashcards. This is a high-frequency topic, so it is worth revising until the explanation feels precise and repeatable. It is section 4 of 7 in this topic. Use this study notes to connect the idea to the wider topic before moving on to questions and flashcards.
