No, you cant have multiple applications sharing the same applicationStorageDirectory - the folder name is taken from the application id, and each app id should be unique.
If you want multiple apps to use the same folder, use File.documentsDirectory or File.userDirectory (or even File.desktopDirectory if you like).
Also, the text of your question suggests you have spaces in your app id. The recommended format for app id's is "reverse domain name" - this will mean the id never contains spaces (which is a good thing) and that you can be reasonably confident that no one else has released an app with the same id (again, a good thing).
Lets say your app is called "SuperApp" and you have a domain name "www.superdomain.com" - you would give your app an id of "com.superdomain.superapp"; thats the domain name in reverse (without the www) followed by the application name.
