Is it possible to prevent a file being renamed in the iTunes File Sharing?

I have an app which uses a sqlite db, saving it in the Documents directory.

Moreover it allows users to create a csv file from the db and send it via email. This .csv file is also saved in the Documents dir.

I would enable the iTunes File Sharing, so users can also save these files on pc/mac (maybe in the future my app could also read the files added by the users).

I read that users can开发者_JAVA技巧 remove, save, add and rename files via iTunes File Sharing, but I noticed that I didn't succeed in removing my app files via iTunes File Sharing, I can only save/add and rename them.

If the remove isn't possible, this is good for my app, but the user can still rename the .sqlite file.

Is there a way to prevent a file being renamed in the iTunes File Sharing?

You can hide the sqlite file from iTunes File sharing by starting the filename with a dot (.)
