User documentation
These zip archives and the website are intended to be (relatively) user-friendly. Basically you have to do :
Using website ("http://tuxa.sme.utc/~nf29a009/NF29-XmlConverter")
uploading your freemind file (if you haven't any hdoc file, three samples are already uploaded).
click file and select convert -> convert_in_HDOC -> run conversion.
click file and select convert -> convert_in_Opale -> run conversion.
if everything worked well, you should now see a new file which ends with ".scar". or "hdoc" Download it.
if you get an error message, please contact the website administrator.
Import the .scar file into Opale
