I found the user files at C: \ Users \ <MyUsername> \ AppData \ Roaming \ Quest Software \ Toad For Oracle \ 11.0 \ UserFiles.
From this folder, I ran this simple one liner from a command line to output the contents to a .TXT file:
DIR /OD > C:\MyDataDir\Toad_UserConfiguration_Files.txt
Then I went one level deeper to: C:\Users\<MyUsername>\AppData\Roaming\Quest Software\Toad for Oracle\11.0\User Files\GUISettings
and ran this from a command line to create another TXT file of the contents of this folder:
DIR /OD > C:\MyDataDir\Toad_UserConfiguration_Files_GUISettings.txt
Save off these folders somewhere and re-load them should you need to re-install Toad.
