.YDB File

The ydb file extension is reported to be used in Yutori 7 program for its default document format. Looks like it is some Japanese education software, no further information could be found.

This ydb file type entry was marked as obsolete and no longer supported file format.

This type of file is no longer actively used and is most likely obsolete. This is typically the case for system files in old operating systems, file types from long discontinued software, or previous versions of certain file types (like documents, projects etc.) that were replaced in higher versions of their original programs.

How to open:

Use Yutori 7 to work with *.ydb files.
