There are several ways to upload files and folders into Google Drive. Using Google Drive for Desktop is the quickest and easiest method of uploading large amounts of files at once.
If you do not already have Google Drive for Desktop on your PC, download and install it here. If you need assistance with installation, please contact the Help Desk.
Open File Explorer on your PC.
Expand your Google Drive folders - you can create a specific folder(s) for the files you are moving if you’d like.
Select the files you want to move. Holding the CTRL key while clicking allows you to select multiple files.
Drag the files into the appropriate folder in your Google Drive.
Depending on the size of the content, it may take quite a bit of time to upload. Consider uploading smaller batches of folders/files at a time instead of the entirety of your files.
