You need to use javascript to show the name of the choosed file, as written in the documentation: https://getbootstrap.com/docs/4.5/components/forms/#file-browser

Here you can find the solution: Bootstrap 4 File Input

That's the code for your example:

<html lang="en">
    <head>
        <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" integrity="sha384-rwoIResjU2yc3z8GV/NPeZWAv56rSmLldC3R/AZzGRnGxQQKnKkoFVhFQhNUwEyJ" crossorigin="anonymous">
        <script src="https://code.jquery.com/jquery-3.1.1.slim.min.js" integrity="sha384-A7FZj7v+d/sdmMqp/nOQwliLvUsJfDHW+k9Omg/a/EheAdgtzNs3hpfag6Ed950n" crossorigin="anonymous"></script>
        <script src="https://cdnjs.cloudflare.com/ajax/libs/tether/1.4.0/js/tether.min.js" integrity="sha384-DztdAPBWPRXSA/3eYEEUWrWCy7G5KFbe8fFjk5JAIxUYHKkDx6Qin1DkWx51bBrb" crossorigin="anonymous"></script>
        <script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/js/bootstrap.min.js" integrity="sha384-vBWWzlZJ8ea9aCX4pEW3rVHjgjt7zpkNpZk+02D9phzyeVkE+jo0ieGizqPLForn" crossorigin="anonymous"></script>
    </head>
    <body>
        <div class="input-group mb-3">
            <div class="custom-file">
                <input type="file" class="custom-file-input" id="inputGroupFile02"/>
                <label class="custom-file-label" for="inputGroupFile02">Choose file</label>
            </div>
            <div class="input-group-append">
                <button class="btn btn-primary">Upload</button>
            </div>
        </div>
        <script>
            $('#inputGroupFile02').on('change',function(){
                //get the file name
                var fileName = $(this).val();
                //replace the "Choose a file" label
                $(this).next('.custom-file-label').html(fileName);
            })
        </script>
    </body>
</html>

If you want you can use the recommended Bootstrap plugin to dynamize your custom file input: https://www.npmjs.com/package/bs-custom-file-input

This plugin can be use with or without jQuery and works with React an Angular

```
$(document).on('change', '.custom-file-input', function (event) {
    $(this).next('.custom-file-label').html(event.target.files[0].name);
})
```
Best of all worlds. Works on dynamically created inputs, and uses actual file name.

I have used following for the same:

<script type="application/javascript">
    $('input[type="file"]').change(function(e){
        var fileName = e.target.files[0].name;
        $('.custom-file-label').html(fileName);
    });
</script>

When you have multiple files, an idea is to show only the first file and the number of the hidden file names.

$('.custom-file input').change(function() {
    var $el = $(this),
    files = $el[0].files,
    label = files[0].name;
    if (files.length > 1) {
        label = label + " and " + String(files.length - 1) + " more files"
    }
    $el.next('.custom-file-label').html(label);
});

Johann-S solution works great. (And it looks like he created the awesome plugin)

The Bootstrap 4.3 documentation example page uses this plugin to modify the filename: https://github.com/Johann-S/bs-custom-file-input

Use the Bootstrap custom file input classes. Add the plugin to your project, and add this code in your script file on the page.
```
$(document).ready(function () {
  bsCustomFileInput.init()
})
```
