How to Use

There are three ways to open a file as hex

Trigger the command palette (Ctrl / Cmd + Shift + P) -> Reopen With -> Hex Editor
Right click a file -> Open With -> Hex Editor
Trigger the command palette (Ctrl / Cmd + Shift + P) -> Open File using Hex Editor

If you would like to use the hex editor as the default hex editor for certain file types you can add the workbench.editorAssociations setting to your settings.json.

For example, this would associate all files with .hex or .ini to open by default in the hex editor

    "workbench.editorAssociations": [
        {
            "viewType": "hexEditor.hexedit",
            "filenamePattern": "*.hex"
        },
        {
            "viewType": "hexEditor.hexedit",
            "filenamePattern": "*.ini"
        }
    ],
