Google Drive - Not Going Anywhere!
There are many articles similar to the link above that talk about "Google Drive" being discontinued. Google Drive as we know it is NOT being discontinued. You do not have to worry about your files or anything to do with MyTools2Go and Google Drive.
Google offers software to access all of your Google Drive content on your Mac or PC without using a web browser. Your files can be synced or "backed up" on your hard drive as well as the internet. Google is updating the software called "Google Drive" with new and better technology called "Backup and Sync" which will do more and use less disk space. If you never used this software you still do not need it.
If you choose to use that software you can but accessing your files through a web browser will not change.
