I'm a bit confused by the Shift Base Folder to Subfolder and Shift Subfolder to Base Folder options. What I really want to do is simply set a default save location.
For example, I am always reading files from F:\Music. I want to always save to G:\Music. Each time I open up a set of files, I have to go back in and "Change Base Folder" to G:\Music. Can this be set anywhere?
Shift Base Folder is used if the split of the path between Base Folder and the rest of the folders in the path (Sub Folder) is incorrect. If when you load the files BaseFolder is already set to F:\Music then it is correct and you do not need to modify it.
Then simply use Save and Move and select G:\Music instead of Save to save your files.
You can set the default Move folder in Preferences:Save:General:Move Folder
