Does restoring to a single volume in bootcamp deleted the windows xp and restore back to originally that there will be only Mac OS?
Yes
I got AppDelete, do you think it works too?
I dont understand what you mean.. you say simply dray the program in application folder.. then it will delete the whole application?
And to delete the VM I created, where can I delete it??
First, read the Parallels manual to be sure how delete a virtual machine.
Normally, to delete an application, just drag it to the trash. In OS X, (almost) all applications are (almost) entirely contained within the application icon, which is actually a package containing all the relevant files. You can look a the package content by right (control) clicking on the app icon and click "show package content". This is why dragging an app to the trash will entirely delete it from your hdd. Most applications, however, create preference files of just a few kb in your library folder. You don't need to delete these, as they are very very small, and they don't interfere with other apps. On the other hand, if you re-install the deleted app later, you will still have the preferences from when you last had it installed. If you want to have these preference files deleted anyway, you can use spotlight to search for them, and then drag them to the trash. Alternatively, use AppZapper, it does the same thing (it actually uses spotlight as well), just costs a few bucks.
