As a developer, how should I use the special folders in Windows Vista (and Windows 7)?

Question

Where should I save data related to my application? Where should I save configuration files? Where should I save temporary files? Should I do it in \"Documents\"? \"AppData\

Answer 1

AppData should be automatic configuration and profiles, documents should only be user saved files. I would put anything that could be useful in multiple systems in AppData/Roaming, and anything else (machine specific) in AppData/Local or LocalLow. For temporary files, use the Temp directory.
