Google Drive and Google Photos are not going anywhere. If you use Google Drive mostly through a web browser or Photos via Android, you probably won’t notice any changes. What is happening is that the old version of the Drive sync client called “Drive for Mac/PC” will no longer be supported. Users will simply migrate to the new "Backup and Sync" application.
Google's cloud storage platforms -- Google Drive and Google Photos -- are getting new desktop clients. The move comes as a result of Google's desire to combine all of their existing cloud storage solutions into one cohesive app, something they've wanted to do since July.
Moving forward, users who had installed Google Drive and Google Photos on their computers to backup data will be using a new tool called Google Backup and Sync. Meanwhile, enterprise users and G Suite customers will have access to a new upcoming "Drive File Stream" application which officially launches on September 26. In a blog post, Google announced that starting December 11 file sync applications for Drive and Photos will lose official support and shortly thereafter, in March, they'll be removing the applications entirely.
