Google-drive – Is it possible to copy files from (Google Drive) Team Drive to My Drive

If you're comfortable using Google Scripts the following from Amit works well for me. I've looped it with an array of folder names grabbed from a spreadsheet to deal with lots of content.

function start() {

var sourceFolder = "source";//name of the source folder
var targetFolder = "target";

var source = DriveApp.getFoldersByName(sourceFolder);
var target = DriveApp.createFolder(targetFolder);

if (source.hasNext()) {
copyFolder(source.next(), target);
}

}

function copyFolder(source, target) {

var folders = source.getFolders();
var files   = source.getFiles();

while(files.hasNext()) {
var file = files.next();
file.makeCopy(file.getName(), target);
}

 while(folders.hasNext()) {
var subFolder = folders.next();
var folderName = subFolder.getName();
var targetFolder = target.createFolder(folderName);
copyFolder(subFolder, targetFolder);
}  

}

I modified Tom Woodward's script to suite my need. Here it is:

   function listFilesInFolder(folderName) {

   var sheet = SpreadsheetApp.getActiveSheet();
   sheet.appendRow(["Name", "File-Id"]);


//change the folder ID below to reflect your folder's ID (look in the URL when you're in your folder)
    var folder = DriveApp.getFolderById("THIS_SHOULD_BE_YOUR_FOLDER_ID");
    var contents = folder.getFiles();

    var cnt = 0;
    var file;

    while (contents.hasNext()) {
        var file = contents.next();
        cnt++;

           data = [
                file.getName(),
                file.getId(),
            ];

            sheet.appendRow(data);
    };
};

I needed to get only the file name and its file-id, and the simplified version does that.
