I am trying to unmount a mounted volume in case it meets certain conditions and for that I am using the following code.
FileManager.default.unmountVolume(at: URL(fileURLWithPath: convictedFile), options: [FileManager.UnmountOptions.allPartitionsAndEjectDisk, FileManager.UnmountOptions.withoutUI], completionHandler: {(_) in})
When I use this code, it force unmounts the volume. I do not want to unmount it in case the user is still working on any of the files present inside it. Is there any way to check whether the user has any files of the mounted volume open? Thanks.
