Let me try to break it down why this error isn’t very helpful
There is no file called folder.none in either the original folder or the songkong folder. So if I attempted to search for it will not be found.
There is however a file called folder…none (I don’t know why this post is showing 3 dots instead of 2) in the songkong created folder but not in the original folder. Why is songkong even creating this file in the first place?
Why didn’t the error state the correct file label of folder…none (2 dots not 3) rather than folder.none?
In the original folder there is a file called folder…mkv (2 dots not 3). So my question is why is songkong attempting to move and relabel this file from an .mkv to .jpg?
Difficult to make sens of this really, may need to add in more debugging as interim step
Okay I missed the bit about 2 dots rather than three dots
So it is trying to save coverart in the file (or from a link, cant tell which in this case) as an actual file in the album folder (this is a default option on Artwork tab) and although it can create an image it cannot determine the actual format it is written in. If it could have determined this it saves to the album folder as folder.format where format is jpg, png ecetera, because it cant determine it is meant to write folder.none but because of a simple bug that I can see and fix it is writing folder..none.
Also changed the error message from just displaying the folder name to displaying the full folder path.
There is another issue of why it is doing this, but at least this explains the reason why it is writing two dots instead of one (I think the .mkv file was a complete red herring)
