.X86_64 ファイル拡張子

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:

1. Right-click the X86_64 file
2. Select Properties
3. Click the "Permissions" tab
4. 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])

注: 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.
