How to Importing Folders into Google Drive

   If you have many files to upload to Google Drive at once, you can import an entire folder as easily as importing a single file. Just like individual files, you can import folders by the drag and drop method or by importing them through Google Drive directly. However, if you are using a browser other than Google Chrome, there are a few extra steps involved.

Drag and Drop Method 

    To import a folder from the desktop, open your Google Drive. Resize your Google Drive window so that the portion of the desktop containing the file is visible. Then, right click on the file and drag it from the desktop into your Google Drive.

 

 

   Once you have dragged the folder into your Drive, a dialogue box with Upload Settings will open. You can decide whether to convert the files within the folder to Google documents, spreadsheets, presentations or drawings, or keep the files in their original formats. Then select Start Upload.

 

    Finally, a status bar will open at the bottom right hand side of your window, showing you the progress of your upload. When the upload is complete, the folder will appear in your Google Drive.
