Storing settings in the Windows registry
By default TreePad stores its settings in the Windows registry, in the HKEY_CURRENT_USER\software\freebyte folder under the particular version of the program you are using. E.g.,
Since uninstalling TreePad normally destroys these settings, if you need to uninstall TreePad for any reason but keep your settings, just delete the TreePad installation directory. Similarly, if you want to reinstall TreePad but keep your original settings, do not run the uninstall process but simply reinstall TreePad. For a completely clean installation, delete all files from the installation directory before reinstalling.
If you would like to backup your current settings, use the Windows Registry Editor (REGEDIT.EXE) or a similar program to export the folder corresponding to the version of TreePad you are using. In REGEDIT, after selecting the program folder (e.g., HKEY_CURRENT_USER\software\freebyte\TreePadPLUS), go to the program's main menu and click Registry ⁄ Export Registry File. This exports the settings found in the selected key to a .reg file.
To import the settings into the registry (on your current machine or a different machine), double-click on the .reg file in the Windows Explorer to 'execute' it.
For further details on using REGEDIT see Windows Help.
You can also backup your settings by first storing the settings into an Ini file; then make a copy of the ini file to some safe location.
