Before carrying out this operation. Please make sure that you have everything synced and quit insync. The command show below has to be passed in the terminal. For windows there is preference menu in the systray.
For Linux you can follow these steps:
1. Copy the /home/
2. Execute “insync –set-files-path=/new/location/Insync” from the command line.
3. When everything has been synced, quit Insync.
Now whenever you run Insync the new location will be used. Hope this helps.
