How to create symlinks to existing packages in Dropbox after fresh install of Sublime:
– Open sublime and close it again.
– Go to appdata/roaming/sublime
– For Sublime 2: remove the package folders: Installed Packages, Pristine Packages and Packages
– For Sublime 3: remove the package folders: Installed Packages and Packages
– Open cmd (as admin) and do this for the removed ‘Installed packages’. Repeat for the other packages
mklink /D "Installed Packages" "C:\path\to\Dropbox\appdata\sublime\Installed Packages"
