What is a DM2 file?

DM2 files mostly belong to DBDesigner.

The DM2 file is a database diagram file made by DBDesigner. It stores the layout of a data model, which shows tables, keys, and relationships in a structured plan.
Using this file, designers create and review database schemas before actual database implementation.

Key Details provided by FilExt.com:

Purpose: To record and display the design of database structures.

Usage: Open and edit exclusively using DBDesigner.

Functionality: It holds visual representations of tables, primary/foreign keys, and their relations in a proprietary format.

Viewing: Not intended for text editors; the proper tool is required to view and modify it.

DM2 format details:

A file format defines how the data in the file is structured. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening. When there is a problem with a file, the first step to solving it is to determine the file format. Our analysis of the DM2 files produces the following result:

The DM2 file extension is not common and predominantly uses a uniform format. The two most common formats are as follows:

65% of all DM2 files start with the bytes 02 00 E9 03 crucial for this file format. They consist of illegible, cryptic characters. A typical file size is 29 KB. The file type is old but is used even today. The files contain the following words: %atrname%, %dictname%, %entname%, pk_%tablename%, %relname% and Arial. Such DM2 files store data about model, tinh and modelo.
10% of all DM2 files use the same file format, which have the signature DIAMAGZ. They consist of unreadable binary data. The file size is in the range of 2 MB to 53 MB. The following keywords are characteristic: :98765-,+*), DDGGHHJRTU, DIAMAGZ, KJIHGFE=<, U?]_&3, ZVAMIOI\EX[IOBG) and vTZYrJVL.

The remaining 25% of all DM2 files are different files with different signatures, often e.g. Delta Music 2 module. Drag & drop your file here to see the file format and a preview of your DM2 file!
