When I build a Unity project on Android, inside the file folder there are already some files

Unity Engine

In my Unity project I have to save some data inside text files (not the best way to save data but still…), and when I export and install the project on Android I notice that the txt files that I need to create are already created, how is this possible and how can I prevent this from happening? thx in advance

If you reinstall on Android, it doesn’t delete earlier files, assuming your APK signatures match.

Are you creating your files using this path:

Anywhere else probably won’t work.

I actually create my files with application persistentDataPath
