      @dustbro Then why not just:

      fileList = FileSystem.findFiles(dir, "*.mid", false);
      

      Or if you want to keep a local var (if ever you have a good reason)

      fileList = midiFiles;
      

      Can't help pressing F5 in the forum...

        That works too!
        Next question. The array of files are Objects. Tips on converting to string so I can load in the MidiPlayer?
        The files in the array looks like:

        "File: E:\\Company\\Groove 06 - 155 bpm\\Pattern01.mid"
        

        I'm calling

        MIDIPlayer.setFile(fileList[0], 1, 1);
        

        and getting an error:

        API Call with undefined parameter 0
        

        I guess technically I just need to remove

        File: 
        

        from the file name

          @ustk @d-healey Any tips on using replace() ?
          I'm trying to snip the File: part off of the file name.
          using:

          fileList = fileList.replace("File: ", "");
          

          but I'm getting the error:

          Unknown function 'replace'

            replace works on strings, fileList is an array so no replace function there. You'd need to loop through your array of objects and run replace on each one.

              @d-healey here's my attempt:

              //hold file list
              var fileList = [];
              const var formattedNames = [];
              
              const var Browse = Content.getComponent("Browse");
              
              inline function onBrowseControl(component, value)
              {
                  if(value) //if button clicked
                  {
                      //open file broswer
                      FileSystem.browseForDirectory("", function(dir)
                          {
                              //push midi list into array
                              fileList = FileSystem.findFiles(dir, "*.mid", false);
                              
                              for (i = 0; i < fileList.length; i++)
                              {
                                  var newName = fileList[i];
                                  newName = newName.replace("File: ", "");
                  
                                  formattedNames.push(newName);
                              }
                              
                          });
                  }
              	
              };
              
              Content.getComponent("Browse").setControlCallback(onBrowseControl);
              

              getting this error:

              function not found
              at
               newName = newName.replace("File: ", "");

                filelist is an array of objects. So filelist[i] is an object not a string. Try Console.print(trace(filelist[i])); to see what is contained within your object.

                  It returns

                    @dustbro If you're going to copy and paste things that I write you should check that I've written it correctly ;) Your variable is called fileList, not filelist.

                      fileList

                      giphy.gif

                      I've been sitting at the computer for 13 hours... maybe I need a break.

                      Now that I'm using variables that actually exist in my project, it returns empty:

                      Interface: 
                      

                      Also, thanks for the help. 👍

                        What do you get with Console.print(fileList.length);?

                            Try this in place of your loop

                            for (f in fileList)
                            {
                            	Console.print(f.toString(File.FullPath));
                            }
                            

                            I also notice you're using some vars, always use local in inline functions, and in on init use reg or const. 99% of the time var should not be used except in paint routines, mouse callbacks, timer callbacks, and occasionally a few other places.

                              Now we're talking! that returns the file path correctly

                                @dustbro Yeah it's late here :) the objects in your array are all file objects so you have access to all of the File class functions, like toString()
