android - List of files of saved to the internal storage

Question

My android application is saving some stats to internal storage. Each file name is in the format of "appname-currentDate"

I was wondering:

1. When I save to internal storage, is there a specific folder assigned to my app, or are my files saved along with files from other applications in the same directory.
2. Is there a way to know the list of files saved by my application to the internal storage

Thank you so much.

Answer 1

1) Depends on which method you use to get the file handle. Normally files are stored in an application specific directory, eg. /data/data/[your.package.name]/. The files in that directory are only readable by your application.

2) Use the getFilesDir() method in your Activity to get a File handle and use the listFiles() on it to get an array of File representing all files in your application data folder.
