Either way, the file likely holds data like 3D scenes or maps, but the two EPC files are otherwise unrelated to each other, other than the fact that they're both used for a PC game. An EPC file may instead be an EPC Tools Diagram file, which is an XML-based file used to store diagrams. Another type of EPC file is one that holds an eBook. We don't have much information on this type of EPC file but it can be assumed it's similar to the EPUB format. How to Open an EPC File EPC files that are associated with the games we just mentioned should open just fine with the Firehand Ember Free image viewer. This, of course, isn't going to open the file in either game, but instead should show you the graphic that the file represents. EPC Tools is a plug-in for Eclipse that can open those types of EPC files. Since these files use the XML format, you should also be able to view the EPC file in any text editor, like Notepad++. Opening this type of file in a text editor may be helpful to some degree, but the EPC file is probably best viewed through the EPC Tools plug-in. We haven't been able to test this, but an EPC file that's an eBook file might be able to open in the same applications that work with EPUB files. However, you most likely have to rename the .EPC file to .EPUB so that the program will recognize the file. AlReader is one mobile app (for Android) that supports EPC files that have been renamed to EPUB. If your EPC file doesn't seem to work with either program, it might be completely unrelated to either of the formats just mentioned. One thing you can do to help figure out what software can open the EPC file is to attempt to view its contents in a text editor like Windows Notepad or Notepad++. If some of the text is readable in a text editor, especially some of the file at the very beginning, then you might be able to use that information to research the program that created your EPC file as well as what can be used to open it. If all of the text is legible, then your EPC file is a text-based file that can be opened with any text editor. If you find that a program on your computer opens EPC files when you double-click on them, but it's the wrong program or not the one you want to use, change the default program for a specific file extension in Windows. How to Convert an EPC File I have little confidence that an EPC game file can be converted to any other format. Especially considering that the format is used only in the two games mentioned above, they probably have no practical use existing in any other format. The XML format that some EPC files are saved in should probably remain in their original format so they can be used with the EPC Tools plug-in. However, you can surely convert them to another XML-like format using a text editor or XML viewer. What we said above about renaming an .EPC eBook to .EPUB is probably the best way to convert that type of EPC file to a new format. However, the act of renaming the extension doesn't actually convert the file. Once it's in the EPUB format, you can use a free document converter like Doxillion to convert the eBook to DOCX, HTML, PDF, and other text-based formats. You cannot usually change a file extension (like the .EPC file extension) to one that your computer recognizes (like .JPG) and expect the newly renamed file to be usable. An actual file format conversion must take place in most cases, which is usually possible with a free file converter.
