Where are Dynamo Backups Stored?

Here:

C:\Users\%username%\AppData\Roaming\Dynamo\Dynamo Revit\backup\

Copy and paste the above link into your Windows Explorer.

Each Dynamo script has one backup that is created and overwritten whenever a file is saved.

Dynamo makes an automatic backup every 1 min your script is open after 5 mins of it being open.

To see if backups are being saved, pull down the console by going to View > Show Console or pressing Ctrl+Shift+Up.

All backups are saved in the same folder regardless of their version.
