## Common questions

**Who can convert a file?**

Only the owner of the file, in their own Storage. People you share an old-format file with always get it read-only until you convert it.

**What if the conversion fails?**

You see "Conversion failed" and "Nothing has been changed." Click **Open read-only** to read the file as it is.
