## FAQ

### Does removing comments also remove the replies attached to them?

Yes. A comment and its replies form one thread, so removing the parent removes the thread. Remove replies individually first if you want to keep the original comment.

### Which presentation formats can comments be removed from?

PPT, PPTX, PPS, POT, PPSX, PPTM, PPSM, POTX, POTM and ODP.

### Are comments actually deleted from the file, or just hidden?

They are removed from the presentation and are not recoverable from the saved file — which is the point when a deck is being prepared for people outside the organisation.

### Can I remove comments from one author only?

Yes. Comments are grouped by author, so a single author's comments can be removed while the rest of the review history stays intact.
