Hi Phil K,
I'm going to need you to be very specific if I'm to help you resolve this issue.
I just tested the process, and it's working, so I need to know your step by step process. For Example, here is mine.
1) Launch Nero Express
2) Select Data->Data Disc
3) Select a folder from My Documents called 'TEST'
4) Go to Finall Burn Window and select option for 'Allow files to be added later'
5) Now Burn
6) Close Nero Express after burn is succesful and disc is ejected
7) Re-insert disc I just created
Add files and folders to the My Documents->Test folder
9) Launch Nero Express again
10) Select Data->Data Disc
And at this point Nero Express checks for new files and folders contained in the Test Folder and a popup window comes up telling me what new folders have been added, and what files have been changed/removed since last write. (See below excerpt of message I get in the pop-up window)
---------------------------
Nero Express
---------------------------
Refresh complete!
0 files/folders have been removed,
4 files/folders have been added,
and 1 files/folders have been replaced.
---------------------------
OK
---------------------------
As far as I can tell, the process is working normally.
A few questions:
1) You say you have Nero 66, do you mean Nero 6.6.0.6?
2) Are you selecting files from the DeskTop? This feature does not work with files on the DeskTop, it must be a Folder on the DeskTop with files contained within. Only then will the refresh feature work.
Regards
Craig
