Thanks. As per my other post 'How to set up MMbackup?' I don't get any dialog when I run the Backup add-on, so cannot make or check whatever settings are necessary. It just gives that error message when it runs.

It's frustrating because it was working before I started trying to sort out my old playlists.

Scripts, Extensions and Addons are different names for the same thing. Tools > Extensions shows all that have been installed. Otherwise it's up to the Addons author as to where in MediaMonkey you can access and use the Addon. Some are Panels, some run through Auto-Tag from Web, others will have entries in the Menu or Context Menu, some will have entries in Options for configuration.

You can install most Addons by running the downloaded installer .MMIP file. This will open them with MediaMonkey for installation (or updating). You can also D&D .MMIP files on to the Player in MediaMonkey or use Tools > Extensions.

What is the difference between an Extension and a Script? They seem to appear in different parts of the program. I have just two entries under [b][i]Tools > Extensions[/i][/b] and seven under [b][i]Tools > Scripts[/i][/b], which includes the two 'extensions'. I added the latter myself. And is [b]Add-On[/b] yet another term for Extension? (The one chosen for this forum section, I note.) Do they all three simply mean the same entity, namely a [b]Script[/b].

I have many [u]more[/u] than seven scripts in one place or another. Should they all be in one folder? Why are they not listed under [i]Tools > Scripts[/i]? Is [i]Tools > Extensions[/i] the only place to add 'new' scripts to [i]Tools > Scripts[/i]? Does this overwrite older vesions of those scripts?

Is there one place all this sort of guidance is documented?
