Ah huh. Figured it out. Thank you very much you 2 for pointing it out. Now I can do what I am trying to do to organise my contents.
Here is what it was for anyone interested, especially reallusion.
When you right click on a file and select create shortcut, the shortcut gets the same name with
- Shortcut on the end.
For all the contents shortcuts I created that way when I first started (before I made my shortcut creater and modifier) I wrote another program to remove some text from files names in a folder and its subfolders.
So I removed - Shortcut from all the content shortcuts and that works fine.
When I did the folder shortcuts that worked I was just testing that it would work so I didn't remove the - Shortcut and it worked fine.
When I started creating the folder shortcuts I actually want I removed the - Shortcut and they don't work.
I just created a new folder shortcut and left - Shortcut and it works in iClone 7.21. So I was wrong, its not the new version that caused the problem. It's just the problem I made occurred just after I updated iClone and stupid me jumped into blaming reallusion's new version of iClone instead of myself.
