What is an EDS File?

Question: What is an EDS File?

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

Before you can open an EDS 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 .EDS file extension refers to.

Answer: A file with the EDS file extension is an Electronic Data Sheet file.

Electronic Data Sheet files are based on the CANopen standard and used to specify various descriptive and communication data for hardware devices, usually those within industrial automation systems.

XDD files are an XML based format specified in the newest CANopen standard and will eventually replace EDS files.

The Ensoniq SQ80 Disk Image format also utilizes the EDS extension.

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

How To Open an EDS File:

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

EDS files can be viewed, created, and tested with the free CANeds program.

A free command line program, called CANchkEDS, is also available that can check the validity of an EDS file. CANchkEDS is included as part of the free CANeds tool I linked to above.

Tip: Use Notepad or another text editor to open the EDS 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 EDS files but it's worth a try.

If you find that an application on your PC does try to open the EDS file but it's the wrong application or if you would rather have another installed program open EDS 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 EDS File:

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

The first option involving opening the EDS 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 EDS files, a third-party file conversion tool (the second option) could be very useful.

Important: You cannot usually change a file extension (like the EDS 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.
