For changing the language of the file browser  As an alternate to what ZimSystem mentioned  override the CSS   a more elegant solution is suggested by the bootstrap docs  build your custom bootstrap styles by adding languages in SCSS Read about it here  https   getbootstrap com docs 4 0 components forms  file-browser  Note  you need to have the lang attribute properly set in your document for this to work  For updating the value on file selection  You could do it with inline js like this       lt label class  custom-file  gt         lt input type  file  id  myfile  class  custom-file-input  onchange    this  next   after   text   this  val   split       slice -1  0    gt         lt span class  custom-file-control  gt  lt  span gt      lt  label gt    Note  the  split       slice -1  0  part removes the C  fakepath  prefix

Updated 2021 Bootstrap 5 Custom file input no longer exists so to change Choose file    you d need to use JS or some CSS like this  Bootstrap 4 4 Displaying the selected filename can also be done with plain JavaScript  Here s an example that assumes the standard custom-file-input with label that is the next sibling element to the input    document querySelector   custom-file-input   addEventListener  change  function e     var fileName   document getElementById  quot myInput quot   files 0  name    var nextSibling   e target nextElementSibling   nextSibling innerText   fileName     https   codeply com p LtpNZllird Bootstrap 4 1  Now in Bootstrap 4 1 the  quot Choose file    quot  placeholder text is set in the custom-file-label   lt div class  quot custom-file quot  id  quot customFile quot  lang  quot es quot  gt           lt input type  quot file quot  class  quot custom-file-input quot  id  quot exampleInputFile quot  aria-describedby  quot fileHelp quot  gt           lt label class  quot custom-file-label quot  for  quot exampleInputFile quot  gt             Select file             lt  label gt   lt  div gt   Changing the  quot Browse quot  button text requires a little extra CSS or SASS  Also notice how language translation works using the lang  quot  quot  attribute   custom-file-input    custom-file-label  after       content   quot Button Text quot      https   codeply com go gnVCj66Efp  CSS  https   codeply com go 2Mo9OrokBQ  SASS  Another Bootstrap 4 1 Option Alternatively you can use this custom file input plugin https   www codeply com go uGJOpHUd8L file-input  Bootstrap 4 Alpha 6  Original Answer  I think there are 2 separate issues here    lt label class  quot custom-file quot  id  quot customFile quot  gt           lt input type  quot file quot  class  quot custom-file-input quot  gt           lt span class  quot custom-file-control form-control-file quot  gt  lt  span gt   lt  label gt   1 - How the change the initial placeholder and button text In Bootstrap 4  the initial placeholder value is set on the custom-file-control with a CSS pseudo   after element based on the HTML language  The initial file button  which isn t really a button but looks like one  is set with a CSS pseudo   before element  These values can be overridden with CSS    customFile  custom-file-control lang en   after     content   quot Select file    quot       customFile  custom-file-control lang en   before     content   quot Click me quot      2 - How to get the selected filename value  and update the input to show the value  Once a file is selected  the value can be obtained using JavaScript jQuery      custom-file-input   on  change  function        var fileName     this  val        However  since the placeholder text for the input is a pseudo element  there s no easy way to manipulate this with Js jQuery  You can however  have a another CSS class that hides the pseudo content once the file is selected     custom-file-control selected lang en   after     content   quot  quot   important     Use jQuery to toggle the  selected class on the  custom-file-control once the file is selected  This will hide the initial placeholder value  Then put the filename value in the  form-control-file span        custom-file-input   on  change  function      var fileName     this  val        this  next   form-control-file   addClass  quot selected quot   html fileName       You can then handle the file upload or re-selection as needed  Demo on Codeply  alpha 6
