Most users start using odrive by linking their storage and then accessing the linked storage through the “odrive” folder in your user’s home directory (either ~/odrive on Mac or something like C:\Users<My User>\odrive on Windows).
So let’s say your Windows user name is Neel and you have linked your Google Drive folder and are using sync on Windows. If you go to C:\Users\Neel\odrive\Google Drive\ to access the files on your Google Drive account, then the free version of our product should work for you fine. (This is what I meant by “operating out of your odrive folder”).
Let’s say you have advanced needs. You have an application running that spits out reports to the C:\Reports\ folder which you want to sync with the “Reports” folder within Google Drive. You could, from time to time, manually move files from C:\Reports\ into your C:\Users\Neel\odrive\Google Drive\Reports\ folder to get these files up to Google Drive. The free version of the product will continue to work fine for that. But if you wanted to leave those report files in place and just tell odrive to sync C:\Reports directly into your “Reports” folder on Google Drive, then you would use the Premium feature for that (you can right-click on C:\Reports and select “Sync to odrive” which will let you choose the remote Google Drive folder you want to sync C:\Reports\ with). This is setting up a sync relationship outside of the odrive folder.
Most people are fine working out of the odrive folder (e.g. C:\Users\Neel\odrive) directly so free sync is just fine. Others choose to upgrade to Premium so they can do more powerful things such as setting up direct sync relationships outside of the odrive folder.
Does that explanation help?
