## FAQ

### Which properties can be read and changed?

Both the built-in document properties — title, author, subject, keywords, company, created and modified times — and any custom properties the deck carries.

### Does editing metadata rewrite the whole presentation?

The file is saved again, so its bytes change, but the slides themselves are untouched. Only the property values differ.

### Can I strip identifying metadata before sharing a deck externally?

Yes — clearing author, company and custom properties is a common pre-publication step. Note that comments and speaker notes are separate; removing them is [annotation](/slides/annotation/) work, not metadata work.

### Is the modified date updated automatically when I save?

Not on its own — it is a property like any other. Set it explicitly if you want it to reflect the change your code just made.
