To remove a file from being available offline:
- Open the Dropbox mobile app.
- Tap the ☑ (more options) next to the file name.
- Toggle Make available offline to the off position.
Tapping the highlighted offline icon (white checkmark in a green circle) while previewing a file will also remove it from offline access.
