Workspace is a Vscode concept to collect several folders at a time. Dendron uses it for some basic configuration. A vault is a Dendron concept and basically a collection of your notes. You can have multiple vaults in Dendron and they would reside in a single workspace but I'd recommend sticking to a single vault for the beginning. If you delete a vault from the file system you should also delete the entries in the two configuration files

dendron.code-workspace

and

dendron.yml

. You can also start over and create a new workspace and vault by running the command

Dendron: Initialize workspace

. If you do this you can copy existing notes into the new location. After that run

Dendron: Doctor

with the option

fixFrontMatter

and

Dendron: Reload Index

.
