To backup your Direct FTP database, you simply need to copy the file to a secure location. Once you do that, you can then install Direct FTP on the new system and copy the file back. Here is where the database is located:
Windows XP: C:\Documents and Settings[username]\Application Data\SharedSettings.ccs
Windows 8/7 & Vista: C:\Users[username]AppData\Roaming\SharedSettings.ccs
Right-click the Shared Settings file and select Copy .
Paste the Shared Settings file into an external data storage device (thumb drive, external hard drive, CD-ROM, etc.) by opening the data storage device, right-clicking the background, and selecting Paste.
