1. yes, but the directories need to exist within the "google drive" folder created on your computer.
2. no scheduling involved - if you update a file in any of the folders you have in the google drive on your computer it is automatically updated to the cloud drive providing you have internet access. If you update on the computer when not connected, it will synch to the cloud drive the next time you connect to the internet. Same applies to any other computer that you have set to synch the files so for instance you have two computers (A and B), updating a file on computer A automatically synchs to the cloud (if internet connection available or next time you connect to the internet). If computer B is connected to the internet the file updated on A will also be automatically synched on B or it will be next time computer B is connected to the internet.
3. you can synch an account on as many computers as you want, you just have to install the drive software and configure it the same on all the computers and login under the email address for the drive...
