InDesign preferences and support files 

The preference and support files for InDesign have similar locations. These files are primarily grouped into three locations, though there is data in additional locations as noted below.

• The application folder: At the location of the application or executable, are subfolders for presets and other support files. These subfolders are typically where the default presets are located.
• The application "roaming data folder": This folder is intended for "normal" preference data that you would want to roam from machine to machine in a roaming profile environment.
• The application "local cached data folder": This folder is designed for large data caches that you don't want to roam from machine to machine in a roaming profile environment on Windows. It is also for data that can be easily regenerated if deleted.
