To Back Up your important PathSolutions files go to:
In your TotalView folder, copy the Data Folder, Notes Folder, Wizard.ini file, and all your Configuration files (.cfg files). You will also want to make sure you copy your Map.jpg if you have created one (located in the Graphics Folder).
Backup all files from the Syslog subdirectory (only required if you use the built-in syslog server). And, Backup all files from the TFTP subdirectory (only required if you use the built-in TFTP server).
After you install PathSolutions on your clean system, copy all those files into the TotalView folder to replace those files there. The Map.jpg file will go back into the Graphics Folder.
