I've seen mention of special folders on the SD card such as "ringtones" and "notifications" .
What is the full list of special folders recognized by Android's (Froyo preferred) configuration and its standard apps?
The information below is from a developer website, it is the closest I could find to a definitive answer.
From website:
If you're using API Level 7 or lower, use getExternalStorageDirectory() to open a File that represents the root of the external storage, then save your shared files in one of the following directories:
* Music/ - Media scanner classifies all media found here as user music.
* Podcasts/ - Media scanner classifies all media found here as a podcast.
* Ringtones/ - Media scanner classifies all media found here as a ringtone.
* Alarms/ - Media scanner classifies all media found here as an alarm sound.
* Notifications/ - Media scanner classifies all media found here as a notification sound.
* Pictures/ - All photos (excluding those taken with the camera).
* Movies/ - All movies (excluding those taken with the camcorder).
* Download/ - Miscellaneous downloads.
Movies
directory and copying .mp4s into it worked like a charm.
