Actually I used one way back when Google didn't give an option to upload any type of file. I used Gmail drive (http://www.filehippo.com/download_gmail_drive/ http://www.filehippo.com/download_gmail_drive/) which creates an actual drive on your computer where you can just put your files and it'll upload to Gmail as an attachment. It's good for files upto 25MB (Gmail attachment size) and if you have inbox issues like me then it's not that a good option. Then there's Gladinet Desktop app (paid) which I have no experience using, here's the link - http://www.google.com/enterprise/marketplace/viewListing?productListingId=1927+12624351498939350646 http://www.google.com/enterprise/marketplace/viewListing?pro...
