android - getExternalFilesDir .. doesn't seem to get deleted during uninstall -

i'm using getexternalfilesdir(environment.directory_movies); store data app needs.

i'm testing eclipse (or exported .apk), , when uninstall app through settings -> apps files not getting deleted.

all documentation , questions have found in stackoverflow seem lead me believe these files should getting deleted during uninstall, still seem exist.

is because it's not installed market? i'm targeting level 10

<uses-sdk     android:minsdkversion="10"     android:targetsdkversion="10" /> 

installing market not seems problem.

the behavior explained getexternalstoragepublicdirectory() method works. sure not calling method instead of getexternalfilesdir() ?

take here http://developer.android.com/guide/topics/data/data-storage.html#filesinternal , section "saving files should shared"

i hope helps
