If you need to copy a Google Drive folder from a web browser, Google will not make it easy for you. However, you can use a workaround or download the desktop app for best practices.
Copying folders with Google Drive (sort of)
Google Drive does not provide a way to copy a folder and all of its content if you use the web-based app. Instead, you must copy the contents of the folder, create a new folder, and then paste everything into the destination folder.
To work around this, start your browser, navigate to Google Drive and open the folder you want to copy. Press Ctrl + A on Windows or Command + A on Mac to select all files. Right-click and then click "Create a copy".
Each file you select will be moved to the current folder, and "copy of" will be added in front of the name of each item.
Now select all file copies, right-click and click "Move to".
Select the directory where you want to save the copies, and then click the New Folder icon in the lower-left corner.
 Give the new folder a name, and then click the checkmark icon.
Finally, click Move Here to move all selected files to this directory.
All your files should be moved to the folder you just created.
T This is a complicated method and should be much easier.
Copying Folders Using Backup and Synchronization
Alternatively, you can copy Google Drive folders directly from the desktop application without the need to open a web browser. This approach is straightforward, unlike the previous method. You simply copy a folder and its contents to a different location – not a silly, cumbersome procedure.
In this guide, we use Backup and Sync for Windows, but it works the same on macOS.
Start the program Start the Backup and Sync desktop app and have all your files and folders sync to the cloud before you start. The symbol should look like this.
After completing synchronization, open File Explorer on Windows or the Finder on Mac Right-click the folder in Google Drive that you want to duplicate, and then click Copy.
Just click the folder, then press Ctrl + C on Windows or Command + C on Mac to copy it.
Next, navigate to the destination directory or to the location where you want to copy this folder. Right-click and then click Paste, or press Ctrl + V on Windows or Command + V on Mac.
The folder is simply copied to the current directory.
Backup and sync instantly sync the folder with Google Drive so you can access it from anywhere.
Until Google integrates the commands for copying and pasting into Drive, you can just copy the two methods above to a folder. Backup and Sync is the simplest and most user-friendly option, but you must first install and properly configure the application on your desktop.
