A file with the EMI file extension is a Pocket Tanks Emitter file used by the Pocket Tanks game. The game is a redesigned version of Scorched Tanks, both of which were created by Michael P. Welch from BlitWise Productions.

Pocket Tanks is a 1 to 2 person game that involves using tanks to shoot explosives across the map in order to attack the opponent. I don't know much about the purpose of EMI files but I suspect they have something to do with storing weapon data.

Two EMI files are included with Pocket Tanks upon installation. One is called default.emi and is located at the root of the program's installation directory. The other is emitter.emi and is stored in the \weapdata\ folder.

Tip: Although it's definitely possible that you're trying to open an EMI file, I think it's more likely that you're after information on opening a file of a similar extension, like an ELM, EMLX/EML, or EMZ file. EMI files just aren't that common.

Note: EMI also stands for electromagnetic interference, external memory interface, and enhanced multilayer image, but none of those concepts are directly related to files that end in EMI.

How To Open an EMI File

EMI files are used by the game Pocket Tanks but aren't meant to be opened using the program interface. They're instead just program files that the game can use when it needs to.

EML files (not EMI, with an uppercase "i") have nothing at all do with Pocket Tanks or any video game, but instead are E-Mail Message files. You can open an EML file using Microsoft Outlook and probably some other email clients.

Tip: If you're definitely working with an EMI file but you know it isn't a Pocket Tanks Emitter file, I recommend opening it with Notepad++.

Using a text editor like Notepad++ to open the EMI file will let you view the file as a text document. If the file is 100% text, that what you have is simply a text file. If only some of the text is readable, then see if you can find a word or two that can help you understand what format the EMI file is in or what program was used to build it.

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

Most file types can be converted using a free file converter, but EMI files are an exception because they're simply not as popular as other files like MP3s, PDFs, etc.

The program that opens a file can sometimes be used to convert the same file to a new format, but that's hardly the case with games, and especially the case with Pocket Tanks since there's no way for you to manually open the EMI file in the program.
