This response led me to Customising Tiddler File Naming feature.
I added this filter to $:/config/FileSystemPaths
[tag[Journal]addprefix[journals/]]
It moves new and edited Journal entries to the journals/ folder.
How do I force TW to automatically move all the old Journal entries into the designated folder.
An obvious solution is the move the files manually from the Operating System’s file explorer. But can it be done via TW?
