If there is folder, i.e. game save folder or sth. that you can’t move under Dropbox folder to continue working, then you can link a folder with dropbox folder to be in sync.
In windows there is a command named ‘mklink’ that enables linking folders.
Here is the usage
mklink [[/d] | [/h] | [/j]] <Link> <Target>
For example to link a game save folder with your dropbox folder:
mklink /D “C:\Users\username\Dropbox\games\My Favourite Game\” “C:\Program Files (x86)\Steam\steamapps\common\My Favourite Game\saves\”
This way your files will be always synced and also versioned with dropbox.
Note: Make sure “C:\Users\username\Dropbox\games\My Favourite Game\” folder does not exist, to allow mklink to create.
Note 2: If you get “Access Denied” error, try opening command prompt with Administrator rights.
