Hi all.

My app uses files to store settings.

I would like to delete those files after a user uninstalls the application.

Is that possible ?

So I am not trying to invoke the uninstall process (because then I know the answer. Instead, I would like my app to clean up after itself when leaving.

if you use persistant store: these files are linked to the application and get removed automatically.
if you use the file system: no clue about it

Thanks for the smile

For the record, here is a link to an DKB article that describes this.

Sorry to be such a noob, but could you please elaborate? I don't see the answer in the link (which I've read previously, of course).

My application (during it's work) deploys 20-30 setting files to the file system. ("file:///store/home/user/someFolder").

Is there a way to 'register' those files so that the native uninstaller knows that that specific folder/files should be removed?

OR

Is there a way to 'listen' to an uninstall event.

Is there a third way ?

(My app is a background app so I could register it as a listener to global events... if that might help)

This can be done if you are using persistent store.  There is no support for this if you are writing files using a FileConnection.

Thank you for the answer.

I (reluctantly) accept it

I heard (and am looking for right now) about a way to receive an uninstall exception, so you can write your own handler to uninstall the files.

I'ts supposed to exist.....
