Go to File > Import > Import Confluence markup from file. Note that you have to select two file locations, one for the markup file and one for the freemind mind-map (we know, this is not perfect).
This method works nice if you have Confluence mounted as a WebDAV directory.
The other way to import Confluence markup is by copying the markup to your clipboard. Then, go to File > Import > Import Confluence markup from clipboard.
Again, you will be asked to select a file location for the freemind mind-map.
Go to File > Export > Export as Confluence markup to file. This method works nice if you have Confluence mounted as a WebDAV directory.
Go to File > Export > Export as Confluence markup to clipboard. Paste the markup into your Wiki page.
You may select the character encoding when importing a file. We do not recommend to change the encoding of the mind-map unless you experience problems.
The plugin remembers the last selected charsets during your session. In order to change the default charsets permanently you can create/edit the file freemind2wiki.conf in your .freemind home directory.
