# Locations
## Old Locations
- on Windows: `C:\Users\USER\AppData\Roaming\obsidian\Custom Dictionary.txt`

# Syncing
When you add words to its dictionary it will be put into a new file outside of your vault directory. So it is not synced.
Obsidian Sync does not support syncing dictionary contents across devices.
