Windows XP: C:\Documents and Settings\<USER>\Application Data\Adobe\InDesign\<Version #>\<language>\ (Note: Prior to version 6 [CS4] the language folder is not used).
Windows Vista or Windows 7: C:\Users\<USER>\AppData\Roaming\Adobe\InDesign\<Version #>\<Language>\ (Note: Prior to version 6 [CS4] the language folder is not used).
Macintosh: Hard Drive/Users/<USER>/Library/Preferences/Adobe InDesign/<Version #>/<Language>/(Note: Prior to version 6 [CS4] the language folder is not used).
