Syncing an already-existing folder on my PC with Google Drive?

[kingmustard]

I have 100 GB space on my Google Account.

 

I have a folder that contains roughly 90 GB of photos, located at E:\Pictures & Photos

 

I want to keep that folder synced with Google.

 

I have installed Google Drive (Windows 10) but I can't figure out how to sync the folder.

 

I don't want to have to move the folder into the Drive folder. That would be silly. I want my folder kept on my physical E:\ hard drive.

 

Any ideas?

Not possible with Google Drive. It can only sync folders that are located in GDrive main folder. It's still also on your drive, GDrive folder is just control point for syncing. You can change or add library's to include GDrive.

A while ago I ran into the same problem and ended up using CloudBerry Backup (it's free). 
Set CloudBerry to backup D:\folder1 to GDrive periodically (see link below), then went to 'Google Drive > Preferences > Sync these folders only' and unticked "folder1" so I wouldn't have two copies of the same files in my computer.
