What is an X86_64 file?
An X86_64 file is a 64-bit executable program file used by the Linux operating system. It contains an application in binary format that is run as an executable, similarly to the .EXE file in Microsoft Windows.
More Information
X86_64 files are typically packaged and distributed with applications. You will most likely encounter the file when downloading a game for Linux. The file is executable and can be opened by double-clicking it. If you receive an error when double-clicking the file, you may need to mark it as "executable."
To enable execution of the X86_64 file, follow these steps:
- Right-click the X86_64 file
- Select Properties
- Click the "Permissions" tab
- Check the "Allow executing file as program" checkbox next to "Execute"
Then type the following from the command-line to execute the file:
./[filename].x86_64 (insert the name of the file in [filename])
NOTE: If Linux still fails to run the X86_64 file, it's most likely dynamically linked to libraries, so you will need to install the missing libraries before the X86_64 file can be run.
