Using Xojo.IO.SpecialFolder.GetResource you get access to the own app resource folders, but how to get access to any other app resources?

For example using the old folderItem system:
f = SpecialFolder.Applications.Child(“AnyAppName.app”).Child(“Contents”).Child(“Resources”).Child(“searchedname”)

i don’t think that’s possible due to sandboxing. At least for iOS.

So using IO is only for IOS, for desktop apps is better the old file system?

You can mix them. Though it’s better to use specialfolder from the old framework on anything other than iOS

the new framework (with xojo.IO) has been made with, and for IOS.
