Fold VS Code regions without forgetting what is hidden

Use folding to focus a reading task

Collapsing unrelated regions can make a long file easier to scan while you investigate one function or section. Choose the region around the cursor deliberately and inspect the fold indicator. Hidden code still exists and can still affect the program, so do not infer that a collapsed part is inactive or irrelevant.

Distinguish one region from the whole file

The single-region commands are useful for a local reading task. Fold All and Unfold All act more broadly. If the file suddenly looks much shorter than expected, inspect the folding state before assuming content was deleted. Language support and indentation can affect which regions the editor recognises.

Return to an expanded review before editing widely

After using a folded view to orient yourself, expand the regions relevant to the planned change. Review hidden surrounding code before applying a larger replacement or moving a block. Practise the fold-and-unfold pair on a harmless file so the visual state is easy to recognise.
