Open IBD File
The IBD extension is used as a database file, and is characteristic of MySQL's default storage mechanism - InnoDB, which allows you to store all tables and indexes in the system table area or in individual files.
This feature is called &ldquo, for multiple &rdquo tablespaces, because each table that is created when this setting is in effect has its own tablespace.
With multiple tablespaces enabled, InnoDB stores each newly created table in its own tbl_name.ibd file in the appropriate database folder.
More about MySQL
MySQL is an open source relational database management system, with various versions, both paid and free.
Its name is a combination of "My", the name of My, the daughter of co-founder Michael Widenius, and "SQL", short for Structured Query Language.
The IBD file is proprietary and cannot be converted to any other format.
The IBD file is of binary type and its manual opening by the user is not recommended.
The IBD file can be compressed to IBZ format, this being a backup of the original database.
