I recently had a laptop hard drive crash and needed to try and recover numerous items including a bunch of FTP sites I had configured for the FileZilla FTP client. The first task was locating the site configuration file on my Windows XP laptop and then understanding how to import the sites to another computer. The site configuration file is named sitemanager.xml and below is the location of this file on Windows XP and on Windows Vista.
FileZilla Site Configuration File Location:
Windows XP:C:\Documents and Settings\<user>\Application Data\FileZilla\sitemanager.xml
Windows Vista: C:\Users\<user>\AppData\Roaming\FileZilla\sitemanager.xml
