What is an MDE file

MDE files mostly belong to ArchiCAD by Graphisoft. An MDE file is an add-on (module) used by the educational version of ArchiCAD architectural design and BIM software. Unlike the educational version, standard versions of ArchiCAD save modules in MOD files. Another type of MDE file is a Standard Jet Database created by Access database management system. It contains a compiled version of an MDB database. Unlike MDB files, an MDE database does not contain editable sources.

How to open MDE files

You need a suitable software like ArchiCAD to open an MDE file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your MDE file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a MDE file directly in the browser:. Just drag the file onto this browser window and drop it.

MDE 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). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So a detailed analysis of a file is vital in order to determine the format and the associated program. Below is our analysis of the MDE files:

The MDE file extension is used very often and mainly uses a special format. The file formats most commonly found in MDE files are:

• 85% of all MDE files save the data in JetDB file format. The JetDB is a database format often used by Microsoft Access and Visual Basic programs. JET is short for Joint Engine Technology. If you open these files in a text editor, you will see only illegible characters. The files are on average 10 MB in size and range from 1 MB to 82 MB. The file type is very old but is also used today. Certain words are almost always found in the files, such as Standard Jet DB. These files are attributed to lucioncd, dataapbdes, genap, exam, manager, system, demo, tuntutan, ganjil, gasal, rseps and track.
• 8% of all MDE files use the same file format, which have the signature EffectData. These are binary files, so they do not contain words or text. MDE files can be up to 15 MB in size, but are often around 260 KB - 12 MB. The files contain the following words: EffectData, ymir work, item and weapon. Files like these are about ridack and wing.

The remaining 7% of all MDE files are different files with different signatures. You can get all the details of your MDE file by dragging it onto this page or by clicking the button "Choose your .mde file to analyze" above.
