What is an EX_ file?

An EX_ file is a Windows executable file renamed from ".exe" to ".ex_". It contains the exact contents of an .EXE file. EX_ files are commonly found on installation CDs, where the installer must first rename the file before executing it.

More Information

Renamed EX_ files are useful for preventing accidental or unwanted execution in Windows. For example, if the user accidentally double-clicks the file, it will not execute by default.

To make an EX_ file executable, rename the ".ex_" extension to ".exe". You can now double-click the file like any other EXE file.
