What is an IDMEF File?

Question: What is an IDMEF File?

Did you find an IDMEF file on your computer and wonder what program should open it? Maybe someone emailed you an IDMEF file but you're not sure how to use it. Perhaps you tried to open the IDMEF file but Windows told you that it could not open it.

Before you can open an IDMEF file (assuming it's even a file format that's intended to be viewed or edited), you'll need to determine what kind of file the .IDMEF file extension refers to.

Answer: A file with the IDMEF file extension is a Snort file.

Other types of files may also use the IDMEF file extension. If you know of any additional file formats that use the .IDMEF extension, please let me know so I can update this information.

How To Open an IDMEF File:

The easiest way to open an IDMEF file is to double-click on it and let your PC decide which default application should open the file. If no program opens the IDMEF file then you probably don't have an application installed that can view and/or edit IDMEF files.

Warning: Take great care when opening executable file formats received via email or downloaded from websites you're not familiar with. See my List of Executable File Extensions for a listing of file extensions to avoid and why.

As of this writing, I don't have information on any specific applications that will view IDMEF files or open IDMEF files for editing. If you know of any, please send me a quick email and let me know the name of the program so I can update this page.

Tip: Use Notepad or another text editor to open the IDMEF file. Many files are text-only files meaning no matter the file extension, a text editor may be able to properly display the file's contents. This may or may not be the case with IDMEF files but it's worth a try.

If you find that an application on your PC does try to open the IDMEF file but it's the wrong application or if you would rather have another installed program open IDMEF files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.

How To Convert an IDMEF File:

There are two main ways to attempt to convert an IDMEF file to another file type:

The first option involving opening the IDMEF file in its native program is preferable because it's both easier and will probably result in a more accurate file conversion. Of course if you don't have a program that opens IDMEF files, a third-party file conversion tool (the second option) could be very useful.

Important: You cannot usually change a file extension (like the IDMEF file extension) to one that your computer recognizes and expect the newly renamed file to be usable. An actual file format conversion using one of the methods described above must take place in most cases.
