I have multiple machines each with filezilla and today I tried to import an updated site manager list to an outdated list on another machine. Unfortunately the sites that were previously in the site manager were not updated but Duplicated.
If you have this problem just look for the sitemanager.xml file, and clear out all theentries.
In windows its located in
Windows 7 & Vista
C:\Users\Yourname\AppData\Roaming\FileZilla\sitemanager.xml
Mac OS X
/users/Yourname/.filezilla/sitemanager.xml
Linux
/home/Yourname/.filezilla/sitemanager.xml
How to sync multiple machines for filezilla sites entries

4. Make a soft link from Dropbox back to your Filezilla folder
Filezilla will still look in it’s default place for the sitemanger file. You’re going to trick it and point it to the file you have snyc’d on Dropbox. You’ll need to open up a Command Prompt (Windows) or a terminal (OS X/Linux) for this step. This is what the commands looked like for me, you’ll need to adjust the file paths as necessary. Note, on Windows, you enter the new link first, then the existing target, and on OS X & Linux, it is the opposite order.
Windows:
mklink “C:\Users\peter\AppData\Roaming\FileZilla\sitemanager.xml” “C:\Users\peter\My Dropbox\Settings\sitemanager.xml”
OS X:
ln -s /users/peter/Dropbox/Settings/sitemanager.xml /users/peter/.filezilla/sitemanager.xml
Linux:
ln -s /home/peter/Dropbox/Settings/sitemanager.xml /home/peter/.filezilla/sitemanager.xml
That’s it! Fire up Filezilla, and you should see the same site settings now on all of your computers. Note, if you use “Synchronized Browsing”, you’ll need to create separate bookmarks under each site for each computer, as the local path to your files will be different depending on your computer.
