Before you open a file
A few practical notes.
- Excel support covers .xlsx workbooks. Password-protected files need to be unlocked first.
- Open images and documents as part of a ZIP archive.
- Exploration is read-only: your original files stay unchanged.
- The size of files you can explore depends on the memory available in your browser.
