问题
[![enter image description here][1]][1]I have made a shortcut (new feature of google) of a google sheets.
Now I want to get all the Spreadsheets I have in a directory:
these function does not work anymore to treat all the Spreadsheet: folder.getFilesByType(mimeType) because the 'new' shortcut a new mime type has been introduced.
The ID of the shortcut is different from the original file. You can not access anymore over ID of the files you find in the directory.
- What is the solution to select only spreadsheets and spreadsheets shortcuts in a directory?
- How to open the spreadsheet a shortcut is pointing at?
    function myFunction() {
      var ss=SpreadsheetApp.getActiveSheet();
      var idRepertoire=ss.getRange("A1").getValue();
      var monRep=DriveApp.getFolderById(idRepertoire);
      var fichiers=monRep.getFiles();
      while (fichiers.hasNext()) {
        var fichier=fichiers.next();
        var parentFichiers=fichier.getParents();
        while (parentFichiers.hasNext()){
          var parent=parentFichiers.next();
          var identiteF=fichier.getId();
          ss.appendRow([fichier.getName(),fichier.getMimeType(),identiteF,parent.getName()]);
          SpreadsheetApp.openById(identiteF).getSheetName("test").getRange("A1"); // causes an error for the shortcut
        }
      }
    }

Both of your questions can be solved by using the Drive API.
Explanation
In order to retrieve all the spreadsheets and the spreadsheet shortcuts, you can use the GET request to retrieve the files:
- For spreadsheet types:
GET https://www.googleapis.com/drive/v3/files
With the following parameter for the q field
mimeType = 'application/vnd.google-apps.spreadsheet'
- For shortcut types:
GET https://www.googleapis.com/drive/v3/files
With the following parameter for the q field
mimeType = 'application/vnd.google-apps.shortcut'
Afterwards, if you want to retrieve the files from the shortcuts above, you can simply do a GET request for each shortcut. So for one shortcut, you can do something like this, where fileId is in fact the id of the shortcut.
GET  https://www.googleapis.com/drive/v3/files/fileId
With the following parameters for the fields field
shortcutDetails
After this GET request, you will receive a response in which you can find the mimeType of the shortcut as well as the original id of the file from the shortcut. 
{
 "shortcutDetails": {
  "targetId": "ID_OF_THE_ORIGINAL_FILE",
  "targetMimeType": "MIME_TYPE_OF_THE_ORIGINAL_FILE"
 }
}
