How do I reset Understand to the default settings?

You can reset Understand to its initial Settings by exiting the program and then renaming the configuration file. On Windows you may have to enable “Show Hidden Files and Folders” first. The configuration file can be found in the following location:

  • Windows 2000/XP – C:\Documents and Settings\USERID\Application Data\SciTools\Understand.ini
  • Windows Vista/7/8/10 – C:\Users\USERID\AppData\Roaming\SciTools\Understand.ini
  • Linux/Unix – ~/.config/SciTools/Understand.conf
  • Mac OS X – ~/Library/Preferences/com.scitools.Understand.plist

Mac’s also require that you run the command

killall cfprefsd

after deleting the file. Otherwise it will just be restored from the cached settings.
