I cannot find the target directory from my unzipped version file from sourceforge. I used 7Zip and WinRar but they both creat an image file that I cannot open up in WinSCP to SSH to my pi.
Try the built-in updater (see your settings menu). Should be available since 0.1.30.
If you’re running an older version please re-read the wiki page. Download the auto-update bz2 and create the .update dir or use the smb share instead.
