Did you find a CES file on your computer and wonder what program should open it? Maybe someone emailed you a CES file but you're not sure how to use it. Perhaps you tried to open the CES file but Windows told you that it could not open it.
Before you can open a CES 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 .CES file extension refers to.
Other types of files may also use the CES file extension. If you know of any additional file formats that use the .CES extension, please let me know so I can update this information.
How To Open an CES File:
The easiest way to open a CES file is to double-click on it and let your PC decide which default application should open the file. If no program opens the CES file then you probably don't have an application installed that can view and/or edit CES 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 CES files or open CES 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 CES 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 CES files but it's worth a try.
If you find that an application on your PC does try to open the CES file but it's the wrong application or if you would rather have another installed program open CES files, see my How To Change the Default Program for a Specific File Extension guide for making that change in Windows.
How To Convert a CES File:
There are two main ways to attempt to convert a CES file to another file type:
- Open the CES file in its default program and choose to save the open file as another file format.
- Use a File Conversion Online Service or Software Program to convert the CES file to another file format.
The first option involving opening the CES 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 CES files, a third-party file conversion tool (the second option) could be very useful.
Important: You cannot usually change a file extension (like the CES 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.
