Modify > Click for Options (top-left of Profile Setup window) > Save as Defaults
There is an option to revert the custom default settings back to the factory default settings under:
Modify > Click for Options (top-left of Profile Setup window) > Revert to factory settings
However, note that both the Save as Defaults and Revert to factory settings options are page specific settings. This means that only the settings on the current page is affected; it does not affect the whole profile.
There may be cases when several settings pages have being saved as defaults in the past, thus making it difficult to identify which settings have been customized before. In such situations, users can choose to delete the default settings configuration file, which will remove all stored custom defaults from the program. Thus, any new profile created after the file is deleted will only have factory settings. This is useful in certain situations. For example, when users have too many custom default settings saved, and would prefer to start over with a clean slate.
If you wish to delete the default configuration file, look for (and delete) the file "DefProfSettings.ini" where it is stored by default in the users private local Application Data folder. This is typically (for pre-Vista versions of Windows)
C:\Documents and Settings\username\Local Settings\Application Data\2BrightSparks\SyncBack
or (for Vista and later)
(In all cases, adjust the final folder to \SyncBackPro if using the Pro version, \SyncBackSE if using the SE version, or \SyncBackFree if using the Free version).
