What is an EX_ file?

EX_ files mostly belong to 7-Zip.

EX_ files are compressed versions of Windows executable files. These files keep the internal structure of a regular .EXE file but are stored in a compressed format to reduce file size and support efficient installation or extraction processes. After you extract the contents, you typically end up with a standard executable that runs on Windows.

Key details provided by FilExt.com include:

• Internal Format: They are based on the Windows EXE format.
• Compression: The file is compressed, so you often need to extract it using specialized tools.
• Usage by various programs: A large share comes from files created by tools like 7-Zip (see 7-Zip website), while others relate to InstallShield and Microsoft utilities like makecab.exe.
• They may appear during software installation or as self-extracting archives.

FilExt.com tip: To open a EX_ file, use a decompression tool that recognizes compressed executables. After extraction, the resulting .EXE file can be run on Windows as usual.

EX_ file format:

To find out what program is needed to open EX_ files, you need to determine the file format. Each file format has a unique extension and almost always a unique signature. For example, Microsoft Word documents have the extension .docx and the signature (usually the first 3 characters in this file) PK. Nonetheless, different programs can utilize the same file extension to represent distinct file formats. Double-clicking on the file often results in an error when opening.
