B4J Question What is the best place to put user files?

[Mikelgiles]

What is the best practice for where to put application files that will be maintained by the user application.
When developing I am just putting them on a sub under dirAPP so I always know where they are.

Does dirAPP end up returning the location where the executable was installed? And if so is that likely to be a problem when writting to files there?

My routine for saving files is:

    Dim Home As String = GetSystemProperty("user.home","")
    If GetSystemProperty("os.name","").ToLowerCase.Contains("win") Then
        Home = Home &"\Documentos"
    End If

    If Not(File.Exists(Home,"pdf")) Then
        File.MakeDir(Home,"pdf")
    End If

DirAPP is good enough too, but sometimes if you put the app in a wrong place (i.e. program files) you may have some troubles writing the folder.

Yes and yes.

The best place for writable files is File.DirData: https://www.b4x.com/android/forum/threads/data-folder.56874/
If the user will need to open the files with another application then it is best to let the user choose the location with FileChooser.
