What is a .ncd file?
A .ncd file is a Nero CoverDesigner File. This is a system or support file. Your computer uses it in the background — it isn't a document. Confusingly, this extension has been used by 2 different formats over the years — they're all listed below.
This extension has been used by more than one format
2 different formats have claimed .ncd over the years, so two files with the same extension aren't necessarily the same kind of thing.
How to open a .ncd file
- Usually nothing. These files are read by the operating system or an application, not by you.
- If it's plain text (settings, logs), a text editor will show its contents safely.
The registry records this extension against Nero CoverDesigner File, Norton Change Directory Persistent Cache File, so software from that family is the most likely match.
How to convert a .ncd file
- System files shouldn't be converted. If a program is complaining about one, reinstalling that program is the usual fix.
